Predictive models that changed how we plan. We would not go back.

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

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

Clear-eyed assessment of where we were, followed by a credible plan forward

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 new practice area required document management workflows that did not exist in our current system. We needed them in place before the first client matter opened.

Ad spend efficiency improved 40% without reducing reach. The targeting work was the difference.

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

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

Accessibility improvements that broadened our audience and satisfied our enterprise clients

The platform has been live for six months and is handling three times the transaction volume we scoped for. That is not because we underestimated — it is because the architecture choices made during discovery were genuinely forward-thinking. Most vendors design for exactly what you tell them. This team designed for what you are likely to need. We are already scoping the next phase and there was no question about who we would use.

Project summary

Our previous vendor had left us with a codebase that worked but was nearly impossible to extend. We needed to fix that without stopping delivery to the business.

Custom software that actually solved the problem — not just the stated requirements

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

Grid modernisation funding required us to demonstrate demand-response capability. The ML models existed on paper — we needed an engineering partner to build and deploy them.
