Independent software studio
Software that ships.
Principal-level engineering for teams modernizing legacy systems, shipping AI into production, and tackling the work that needs the senior chair.
01 Selected Work
A fashion-technology platform had outgrown the servers it was built on. We moved it onto modern managed infrastructure with no maintenance window, no weekend cutover, and no change to the running system — building the new production alongside the old one and proving it against real data before anything switched over. Client work, anonymised.
Read the case studyA rostering engine that checks its own work. A constraint solver builds a 13-week hospital roster against a real industrial award; a second, independent implementation re-verifies every clause to the minute — and caught two violations that would have survived any human review. Open source, with a live demo.
Try Rota AIReal neural guitar-amp inference as a drop-in Web Audio node. Loads a Neural Amp Modeler model into any browser audio graph in three lines — no UI framework, no cross-origin headers. A clean-room, MIT-licensed engine on npm as @happysoftware/nam-web.
A merchant tool that surfaces reorder opportunities before stockouts cost revenue. Tracks profit-at-risk by SKU and turns inventory data into action. Live on the Shopify App Store.
View Reorder RadarCron monitoring that catches silent failures. Simple pings, smart alerts, no noise — built for teams who can't afford a job to fail unnoticed.
View Cron CommandoA browser practice room: plug in, hear yourself through a real neural amp tone (powered by NAM Web), and the app grades what you play in real time. Free, no sign-up, runs entirely client-side.
