The redesign made our product feel like a different company built it. In a good way.

Three months post-launch our key metrics are all moving in the right direction — user adoption ahead of target, support volume down, time-on-task reduced for our core workflows. The product team has started planning features that were never viable on the previous platform. That is the real proof of the investment: it opened up possibilities rather than just replacing what was there before.

Project summary

International expansion required multi-currency, multi-language, and multi-warehouse capability our current platform could not support without a rewrite.

Pipeline configuration that maps to how our team actually sells. Revolutionary.

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

A failed engagement the previous year had made us more rigorous about vendor selection. We took the time to find a partner we actually trusted before we committed.

First AR project we have shipped where the frame rate held across every device we tested

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

An enterprise client contract required a level of reporting transparency our existing platform could not provide. Building it was a condition of the renewal.

Deployment frequency tripled. Incident rate halved. Exactly the direction we wanted.

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.

Compliance programme delivered on time and approved without remediation

Our stakeholder group was unusually broad — board sponsors, operational users, compliance leads, and an IT team with strong opinions. I have watched vendors handle that kind of environment badly. This team adjusted how they communicated depending on who they were talking to, managed expectations honestly when things shifted, and delivered something that each group considers a success. Getting everyone to agree on that outcome was not straightforward and they deserve credit for making it happen.

Project summary

A regulatory change required us to rearchitect how we stored and processed customer call data. The timeline was set externally, not by our roadmap preferences.
