Data engineering quality that will support our growth for years without a rebuild

Eoghan Fitzgerald / VP of Engineering - Shannon Tech Solutions Ltd

Jun 10, 2026

Project summary: Our campaign management workflow had grown to involve twelve different tools and significant manual reconciliation. The inefficiency was affecting both speed and accuracy.

The project brief was ambitious and we had received proposals ranging from two to five times our eventual budget from other vendors. This team came back with a proposal that was commercially realistic and technically credible — and then delivered against it. That alignment between proposal and outcome is not something I take for granted. I have been on the other side of it enough times to know it requires both honesty in the sales process and discipline in delivery. We experienced both.

PROS

Architectural decisions designed for longevity rather than just the current brief, thorough automated test coverage, post-launch stability that validated every technical choice made during discovery

CONS

Pipeline availability for kickoff required a few weeks of lead time — in hindsight that selection pressure means you are working with a team that is in demand for the right reasons

Questions & Answers

Please describe your company, your role, and the industry you operate in.

Shannon Tech Solutions Ltd is an established Advertising & Marketing organisation headquartered in Dublin, Ireland. My role as VP of Engineering covers both strategic planning and operational technology delivery. We maintain high standards for our vendors because our clients hold us to high standards — a bar we expect our partners to meet.

What specific problem or business challenge led you to hire this company?

A competitive threat had accelerated our roadmap. We had planned a significant Data & Analytics investment for the following year. External pressure moved that timeline forward by six months and required us to find an external partner rather than attempting to build internally in the time available.

What services did the company provide for your project?

The core engagement was Data & Analytics delivery, though their scope expanded to include technical consultancy during discovery that materially improved our requirements. They also took ownership of the third-party integration workstream that had been a coordination challenge in previous projects, removing that complexity from our internal team entirely.

Why did you choose this company over other providers you considered?

The quality of the questions they asked during the briefing process was the first indicator. Vendors who ask precise questions in the sales phase tend to apply the same rigour during delivery. That hypothesis proved accurate. The technical proposal was substantive, the team structure was senior throughout, and the pricing was transparent.

How clearly did the company understand your requirements and business goals?

Better than we managed ourselves going in. The workshops they facilitated surfaced assumptions we had not examined and exposed three requirements that were in direct conflict with each other. Resolving those before development began saved us what would certainly have been significant rework later in the project.

How was your overall experience with their communication and project management?

Communication was proactive, timely, and appropriately calibrated. Technical updates for the engineering audience, executive summaries for the steering group, risk flags with proposed mitigations rather than just problem statements. The fortnightly sprint reviews gave our stakeholders visibility without requiring them to attend every working session.

Did the company deliver the project on time and within your expected budget?

On time and within the approved budget. The estimation accuracy was notable — they had broken the work down in sufficient detail during discovery that their forecast proved reliable throughout, rather than being a number that shifted with every change in scope. We received one change request and it was for scope we had introduced ourselves.

What tangible results or business impact have you seen since the project was completed?

We went live four months ago. User adoption exceeded the target we had set by 23 percent in the first month. Support ticket volume has dropped measurably. The features we had deferred because the previous architecture made them prohibitively expensive to build are now in development. The platform they built has opened our roadmap.

What did you like most about working with this company?

The continuity of the team. The engineers who participated in the discovery sessions were the engineers who built the system. That consistency of institutional knowledge across a six-month project has a value that is difficult to quantify but easy to notice when it is absent. Every conversation built on the previous ones.

Would you recommend this company to others, and would you work with them again?

Yes. I would add the context that this is not the cheapest option in the market and they are selective about the engagements they take on. If your primary criterion is price, there are alternatives. If you want a technology partner who can be trusted with a complex Data & Analytics programme in the Advertising & Marketing space and will deliver against a serious brief, this is the team.

Penetration test that found things our previous vendor had missed for two consecutive years

Project summary: Evolving open banking obligations required us to rebuild our API layer from the ground up. The architecture needed to be compliant by default, not bolted on after the fact.

We had worked with three agencies before this engagement. The comparison is not flattering to the others. What distinguished this team was a systematic approach to understanding the problem before proposing a solution — something that sounds obvious and is practiced far less often than it should be. The delivery phase ran to schedule, the codebase is clean enough that our internal engineers made positive comments during handover review, and we have not logged a critical incident in five months of live operation. We intend to use them for our next phase of work.

PROS

Collaborative culture that made the team feel like a genuine extension of our organisation, strong asynchronous communication across time zones, zero-drama handling of the inevitable mid-project changes

CONS

The quality of documentation they produce means our team needed to set aside dedicated review time to do it justice — a minor scheduling point rather than a genuine criticism

Questions & Answers

Please describe your company, your role, and the industry you operate in.

I lead technology at Lumière Technologies SAS, a growth-stage Financial Services business based in Paris, France. As Directeur Technique my remit spans product engineering, platform operations, and strategic vendor partnerships. We had reached an inflection point where our internal capacity was not sufficient to execute our roadmap at the pace our market required.

What specific problem or business challenge led you to hire this company?

The immediate problem was that our Cybersecurity capability had become the bottleneck limiting our ability to grow. Every feature request, every new client requirement, every internal initiative was delayed by a platform that had been extended beyond its original design. We needed a rebuild, not a patch.

What services did the company provide for your project?

The core engagement was Cybersecurity delivery, though their scope expanded to include technical consultancy during discovery that materially improved our requirements. They also took ownership of the third-party integration workstream that had been a coordination challenge in previous projects, removing that complexity from our internal team entirely.

Why did you choose this company over other providers you considered?

A trusted peer in the Financial Services sector had used them for a comparable Cybersecurity engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, Cybersecurity depth, and demonstrated delivery discipline was the deciding factor.

How clearly did the company understand your requirements and business goals?

Better than we managed ourselves going in. The workshops they facilitated surfaced assumptions we had not examined and exposed three requirements that were in direct conflict with each other. Resolving those before development began saved us what would certainly have been significant rework later in the project.

How was your overall experience with their communication and project management?

Outstanding. The discipline around asynchronous communication was particularly effective given the time zones involved between Paris, France and the delivery team. Written updates were specific and consistent, response times were same-day for anything that required a decision, and nothing fell through the cracks across a six-month engagement.

Did the company deliver the project on time and within your expected budget?

Yes to both. There was a single sprint where a dependency on a third-party API introduced a one-week delay. The team identified it three weeks in advance, presented two mitigation options, and we agreed on an approach that recovered the schedule within the same sprint cycle. That level of foresight is what separates good project management from reactive problem management.

What tangible results or business impact have you seen since the project was completed?

Quantifying the impact precisely is complicated by other variables in our business, but the metrics we can attribute directly to the Cybersecurity work are meaningful: session duration up, conversion rate up, error rate down, and our NPS for the digital touchpoint has improved by eleven points. Our account managers report that the new capability is coming up positively in client conversations.

What did you like most about working with this company?

Their instinct for keeping the business objective visible throughout technical decision-making. I have worked with technically excellent teams who lose the strategic thread as complexity increases. This team maintained a clear connection between every architectural choice and the outcome we had agreed to achieve. That orientation made the trade-off conversations significantly easier.

Would you recommend this company to others, and would you work with them again?

Unreservedly. We are in active scoping conversations for a second engagement and I expect this to develop into a multi-year partnership. For any organisation in the Financial Services sector looking for Cybersecurity expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

Multiplayer infrastructure that held through a launch-day traffic spike we had not fully anticipated

Project summary: Our internal product thinking was strong but our execution capability in this specific technology domain was limited. We needed depth, not generalism.

The integration layer was the part of the project I was most concerned about going in. Our system landscape is complex, several of the upstream APIs we relied on were poorly documented, and two third-party vendors had a history of unpredictable response times on integration questions. This team managed all of that. They documented what the upstream vendors could not, built resilience into the integration architecture where the upstream behaviour was unreliable, and delivered a solution that works as specified in production. I could not have asked for more.

PROS

Senior-level engineering presence throughout the entire project, not just during the pitch, honest and commercially fair handling of scope changes, codebase that our internal team praised on review

CONS

Time zone coordination required some deliberate overlap management from both sides in the first couple of sprints, after which we had an efficient async rhythm that worked for the whole project

Questions & Answers

Please describe your company, your role, and the industry you operate in.

As Head of Technology at Ravi Digital Agency I oversee technology investment and delivery across our Events & Event Management operations in Lahore, Pakistan. We are a commercially focused business and our technology choices are always evaluated in terms of their direct contribution to business outcomes rather than technical elegance alone.

What specific problem or business challenge led you to hire this company?

A competitive threat had accelerated our roadmap. We had planned a significant Game Development investment for the following year. External pressure moved that timeline forward by six months and required us to find an external partner rather than attempting to build internally in the time available.

What services did the company provide for your project?

End-to-end Game Development delivery with particular depth in the integration and data migration components, which were the highest-risk elements of the programme. They supplemented this with a dedicated QA resource throughout development and a documented runbook for our operations team at handover.

Why did you choose this company over other providers you considered?

The quality of the questions they asked during the briefing process was the first indicator. Vendors who ask precise questions in the sales phase tend to apply the same rigour during delivery. That hypothesis proved accurate. The technical proposal was substantive, the team structure was senior throughout, and the pricing was transparent.

How clearly did the company understand your requirements and business goals?

Better than we managed ourselves going in. The workshops they facilitated surfaced assumptions we had not examined and exposed three requirements that were in direct conflict with each other. Resolving those before development began saved us what would certainly have been significant rework later in the project.

How was your overall experience with their communication and project management?

The project management framework was the most structured I have experienced with an external vendor. Sprint planning was tight, acceptance criteria were specific, retrospectives were honest and acted on. The project manager treated the shared backlog as a live document and the risk register as an operational tool rather than a compliance artefact. I never had to ask for a status update.

Did the company deliver the project on time and within your expected budget?

On time and within the approved budget. The estimation accuracy was notable — they had broken the work down in sufficient detail during discovery that their forecast proved reliable throughout, rather than being a number that shifted with every change in scope. We received one change request and it was for scope we had introduced ourselves.

What tangible results or business impact have you seen since the project was completed?

The most direct measure is the performance of the system in production. In the five months since go-live we have had zero P1 incidents, our page performance scores have improved across every Core Web Vitals metric, and two enterprise clients who had cited our previous platform limitations during contract negotiations have since renewed without that objection arising.

What did you like most about working with this company?

The post-launch behaviour. Some vendors consider go-live to be the end of their professional obligation. This team treated it as the transition to a different kind of engagement. The hypercare period was substantive, the documentation was thorough and genuinely useful, and they checked in proactively at the thirty-day and ninety-day marks to review production metrics with us.

Would you recommend this company to others, and would you work with them again?

Unreservedly. We are in active scoping conversations for a second engagement and I expect this to develop into a multi-year partnership. For any organisation in the Events & Event Management sector looking for Game Development expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

Project summary: An international expansion required multi-currency, multi-language, and multi-warehouse capabilities that our existing platform could not support without a fundamental re-architecture.

The project brief was ambitious and we had received proposals ranging from two to five times our eventual budget from other vendors. This team came back with a proposal that was commercially realistic and technically credible — and then delivered against it. That alignment between proposal and outcome is not something I take for granted. I have been on the other side of it enough times to know it requires both honesty in the sales process and discipline in delivery. We experienced both.

PROS

Questions & Answers

Please describe your company, your role, and the industry you operate in.

Amazônia Digital Ltda is an established Retail & E-commerce organisation headquartered in São Paulo, Brazil. My role as VP of Technology covers both strategic planning and operational technology delivery. We maintain high standards for our vendors because our clients hold us to high standards — a bar we expect our partners to meet.

What specific problem or business challenge led you to hire this company?

Regulatory requirements in our Retail & E-commerce segment had changed and the compliance timeline was set by our regulator, not by us. The CRM Development changes required were significant enough to justify engaging a specialist partner rather than diverting our internal team from the product roadmap.

What services did the company provide for your project?

End-to-end CRM Development delivery with particular depth in the integration and data migration components, which were the highest-risk elements of the programme. They supplemented this with a dedicated QA resource throughout development and a documented runbook for our operations team at handover.

Why did you choose this company over other providers you considered?

We ran a structured shortlisting process across five vendors. The technical evaluation eliminated two immediately. Of the remaining three, this team's proposal was differentiated by the specificity of their CRM Development approach and the evidence base they provided — reference projects in Retail & E-commerce contexts, not generic case studies. The reference calls confirmed a track record that the proposal had described accurately.

How clearly did the company understand your requirements and business goals?

Thoroughly and precisely. The requirements document they produced was detailed enough that our QA team used it directly to write acceptance criteria. Every user story had a defined business objective attached. Nothing was left to interpretation. That discipline in the requirements phase paid dividends throughout development and testing.

How was your overall experience with their communication and project management?

Communication was proactive, timely, and appropriately calibrated. Technical updates for the engineering audience, executive summaries for the steering group, risk flags with proposed mitigations rather than just problem statements. The fortnightly sprint reviews gave our stakeholders visibility without requiring them to attend every working session.

Did the company deliver the project on time and within your expected budget?

Yes. I had privately built a contingency expectation into my planning given the project complexity and the number of integrations involved. None of that contingency was needed. The delivery landed on the agreed date and the final invoice matched the approved budget to within a fraction of a percent. That outcome is rarer than the industry acknowledges.

What tangible results or business impact have you seen since the project was completed?

We went live four months ago. User adoption exceeded the target we had set by 23 percent in the first month. Support ticket volume has dropped measurably. The features we had deferred because the previous architecture made them prohibitively expensive to build are now in development. The platform they built has opened our roadmap.

Yes. I would add the context that this is not the cheapest option in the market and they are selective about the engagements they take on. If your primary criterion is price, there are alternatives. If you want a technology partner who can be trusted with a complex CRM Development programme in the Retail & E-commerce space and will deliver against a serious brief, this is the team.

Project summary: Our campaign management workflow had grown to involve twelve different tools and significant manual reconciliation. The inefficiency was affecting both speed and accuracy.

The thing that retrospectively seems most significant is how little drama there was. Complex technology projects tend to accumulate incidents, escalations, and tense conversations. This one did not. Problems were surfaced before they became incidents. Scope changes were handled with process rather than conflict. Risks were managed rather than avoided. That level of maturity is rare in my experience and it made the delivery feel almost effortless from our side, which I know it was not from theirs.

PROS

Deep domain knowledge that reduced the discovery overhead significantly, proactive risk identification before issues became incidents, delivery cadence that our stakeholders found reassuring

CONS

The quality of documentation they produce means our team needed to set aside dedicated review time to do it justice — a minor scheduling point rather than a genuine criticism

Please describe your company, your role, and the industry you operate in.

Solaris Media Group is an established Advertising & Marketing organisation headquartered in Los Angeles, USA. My role as Chief Product Officer covers both strategic planning and operational technology delivery. We maintain high standards for our vendors because our clients hold us to high standards — a bar we expect our partners to meet.

What specific problem or business challenge led you to hire this company?

A competitive threat had accelerated our roadmap. We had planned a significant Low-Code / No-Code Development investment for the following year. External pressure moved that timeline forward by six months and required us to find an external partner rather than attempting to build internally in the time available.

What services did the company provide for your project?

Primarily Low-Code / No-Code Development, with adjacent work in solution architecture and quality assurance. They were responsible for the full build from requirements through to go-live, including integration with four existing systems in our technology landscape. The breadth they covered without requiring additional vendors was commercially and logistically valuable.
