I fuse creativity and precision at the cutting edge — building AI platforms, architecting clouds, and occasionally hiding pixel creatures behind my own photograph.

Defaux is French — faux, as in fake. And what is faux, if not an imitation? The code, however, is all true.

Systems sketched on napkins, shipped to clouds
Built & rebuilt AI platforms — incl. the public sector's first
03 / selected works
Multi-million-pound public sector transformations — plus one nerdy side quest.
Propositions and proof-of-concept solutions showing public sector clients what Generative AI can actually do: bespoke AWS cloud architectures, foundational software, and GPT-4-powered showcases that modernised technical and customer-support capabilities for genuine service excellence.
Built, stress-tested, torn down and rebuilt. The platform survived full architectural reincarnations on its way to becoming the first successful AI platform delivered for public sector clients — and the blueprint I still measure every platform against.
A production sweepstakes platform for the 2026 World Cup: live brackets, draw management and leaderboards that update as the tournament unfolds. Built end-to-end as a personal challenge and shipped for real players to use all summer.

His technical expertise, energy, and leadership have been central to the success… He has driven discussions about future opportunities and has been crucial to helping us design a realistic, yet comprehensive solution.
The pace at which you delivered features in the run-up to production was truly impressive — your contribution was critical to our success. Nic deep-dives into complex technical issues, not only resolving them but taking the time to coach and mentor.
His leadership as a dev is his standout quality… has not only developed the frontend but also mentored another dev along the way, allowing her to flourish and contribute strongly to the team.
You have solid technical skills, and you take a lot of responsibility… the team clearly trusts and relies on you… you bring a bit of fun and energy to the day-to-day. It's a great mix that really adds to the team.
