A development partner who pushed back when our approach was wrong — exactly what we needed

We have worked with a few agencies over the years and the comparison is honestly not close. What stood out from the start was that they spent serious time understanding the problem before they proposed anything. Once development started, every sprint review was clean — no hidden surprises, no slipped milestones. The production system has been running for four months without a single critical issue. Our internal developers reviewed the codebase at handover and were genuinely complimentary about the quality. That does not happen often.

Project summary

A new care pathway required patient data to move between systems in a way our current architecture did not support. The integration complexity was beyond what we could handle in-house.

The team understood mobile-first before we finished explaining the brief

What I appreciated most was that they were honest when things were not going to plan. There was one point mid-project where a dependency was going to affect our timeline and they told us three weeks before it would have become critical. That gave us time to adjust. Vendors who manage upward proactively are rare. This one did it consistently throughout the engagement.

Project summary

Years of incremental development had left us with a platform that was functional but limiting. A structured rebuild was the agreed path forward.

Finally — ML that our operations team actually uses rather than ignores

Looking back, what strikes me most is how little drama there was. Real technology projects have problems. This one had them too — but every problem was flagged before it became a crisis, every scope change was handled through a proper process, and every risk was managed rather than buried. Our project manager said it was the smoothest vendor engagement he had been involved in. Given how complex the technical requirements were, I think that reflects genuine delivery maturity.

Project summary

Our competitors' checkout experience was noticeably better than ours. Customers mentioned it in return surveys. We needed to close that gap before the next trading season.

Checkout completion rate improved from day one of production. Not week three — day one.

The knowledge transfer at the end of the project was notably good. Too many vendors see handover as a tick-box exercise. This team ran structured sessions, produced documentation our internal team actually references, and spent real time making sure we understood the architecture decisions well enough to maintain and extend the system independently. Six months later we are doing exactly that without needing to go back to them for every question.

Project summary

The business case had been approved but the internal resource to execute it had not materialised. External delivery was the pragmatic solution.

Black Friday traffic spike was the real test. The platform passed without a sweat.

The part of this project I had been most worried about was the integration work. Our system landscape is complex, some of the upstream APIs were barely documented, and one of our third-party vendors was notoriously slow to respond. This team documented what the upstream vendors could not, built resilience into the architecture where third-party reliability was uncertain, and delivered integrations that have worked exactly as specified since day one. I genuinely could not have asked for more.

Project summary

As a technology company ourselves we hold our vendors to the same standard our clients hold us to. Finding a partner who could meet that bar without being hand-held through the process was the challenge.
