ERP went live on the agreed date. Those of you who have been through ERP projects understand.

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

A new commercial property division required tooling that was fundamentally different from our residential platform. Extending the existing system was not viable.

E-commerce rebuild that generated positive ROI before the end of its first quarter live

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.

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.

Finally — ML that our operations team actually uses rather than ignores

What set this team apart in practice was their engineering judgment — specifically, their willingness to tell us when our requirements were wrong and explain what to do instead. Not every vendor does that. The consultative element elevated the final output well beyond what our original brief described. We ended up with something better than what we had asked for, which is not a sentence I expected to be writing in a review.

Project summary

Our client portal had not been updated since 2018. Prospects were mentioning competitor portals in pitches. We could not keep deferring the investment.

The kind of game studio that treats production quality as non-negotiable

I have been through several technology implementations in my career. The pattern I am used to is: detailed proposal, optimistic timeline, scope creep, overrun, excuses at the end. This engagement broke that pattern at every stage. The timeline was realistic from the start. Changes were managed through process. The final delivery matched what was agreed. Simple, but uncommon.

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.

Real-time dashboards that finance and operations both agree on. That alone was worth it.

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 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.
