Our old app had a 2.8 rating. The new one is at 4.6. The comparison is all you need.

The technical quality is the obvious thing to highlight. The automated test suite is comprehensive, the deployment pipeline is solid, and the documentation is actually useful rather than written to satisfy a checklist. But the metric I keep coming back to is what has NOT happened since go-live. No 2am incident calls. No emergency patches. No post-launch retrospectives about what went wrong. For a system of this complexity, that outcome is exactly what we paid for.

Project summary

Warehouse management errors were accumulating at a rate our clients could see. A proper WMS was the agreed fix — we needed a development partner who had built one before.

Delivered what the proposal described. More rare than it should be.

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.

Attribution answers we had stopped asking for — now we get them daily

Honestly, I came into this engagement with some scepticism. We had a bad experience with a vendor twelve months earlier and I wanted to see evidence of competence, not just hear about it. The discovery documentation was the first signal. The sprint delivery consistency was the second. By go-live I had stopped being sceptical and started planning how to expand the engagement. The production system has been stable from day one and our internal team loves working with the codebase they left us.

Project summary

Our internal team was committed to maintenance and could not absorb a new build of this complexity. An external partner was the only way to hit the timeline.

Proposal matched the outcome. That alignment is rarer than vendors acknowledge.

We handed them an aggressive deadline, a complex scope, and a client-side team that was stretched and not always available when they needed us. They handled that gracefully. They were precise about what they needed and when they needed it. Where they could proceed independently they did. The delivery landed on time in spite of the constraints we added. I regard that as strong evidence of genuine professional maturity — not just capability.

Project summary

Our mobile app sat at 2.9 stars. Every negative review mentioned the same two things — speed and checkout complexity. Both were fixable with the right engineering approach.

A vendor that earned a place on our preferred supplier list through delivery, not sales

We went with a smaller team than we had originally planned for. I had concerns about whether the capacity would be sufficient given our timeline. Those concerns were unfounded. The team was focused, communication was constant, and the quality at each milestone review was consistent throughout. Smaller does not mean slower when the people are the right ones and this engagement proved that.

Project summary

Telehealth demand had turned a pilot into a core service line faster than our technology could keep up. We needed a compliant, reliable platform and we needed it quickly.
