Core Web Vitals are green across the board. Our SEO team sent a thank-you note.

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 project had a board-level visibility date. We needed a partner who would treat the deadline as their own.

Pilot to full fleet deployment with zero redesign required along the way

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

Unplanned downtime was our single largest controllable cost. Predictive maintenance data showed we could address most of it — but only with the right data infrastructure in place first.

Headless CMS that let designers and developers finally work in parallel

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.

Went live on time and under budget. Our CFO framed the project charter.

We received proposals from six vendors. Four of them quoted us prices that bore no relationship to the actual scope. This team came back with something realistic and then delivered against it exactly. I have worked on enough technology projects to know that the gap between what is proposed and what is delivered is where trust gets destroyed. There was no gap here. What was promised is what we got, and the ongoing relationship we have built from this is something we intend to continue.

Project summary

Supply chain disruptions had made demand forecasting critical. Our planning team was working off data that was always two weeks out of date.

SEO foundation they built is still generating organic traffic eighteen months later

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

Broker portal satisfaction scores had fallen for two consecutive years. Specific feedback pointed to the same workflow frustrations. We needed a redesign, not a patch.
