What I'm looking for

I'm looking to build practical, well-documented software where I can apply Java, systems design, troubleshooting and AI-assisted development workflows to real operational or product problems.

I've built and released Scrum, a rugby recruitment marketplace connecting players, coaches and clubs, on Google Play and the Apple App Store. At Oh Interactive Studios, I lead product planning, development and releases across React, TypeScript, Capacitor, Supabase, Postgres, Stripe and Apple In-App Purchases.

My background includes more than 20 years supporting operational systems at Wellington Combined Taxis, where I improved reporting, data flows and business-critical tools in a 24/7 operation. Since 2019, I've built Java applications, chess engines, local data tools and AI-assisted development workflows, including CEC, a practical method for keeping software changes controlled, documented and reviewable.
