Technically strong, commercially fair, and genuinely good to work with

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

Open banking changes required us to rebuild our API layer properly — compliant by design, not patched together. We needed specialist engineers, not generalists.

ISO 27001 certification achieved on the first attempt. The preparation was that thorough.

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

A major enterprise client contract required API-level integration with their supply chain platform. We had thirty days to demonstrate capability and our existing system could not provide it.

QA coverage that finally made Friday deployments a professional activity

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

A regulatory deadline required us to modernise how we reported on network performance. The data engineering needed to support it was not something our internal team could absorb without help.

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

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 campaign workflow ran across twelve different tools. The reconciliation overhead was hurting both speed and accuracy, and our team was absorbing the cost.

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

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 new product line required underwriting logic that our legacy system could not support without a rewrite of the rules engine. The workarounds had accumulated to the point of being unmanageable.
