My work

Software I've actually built

Proof of 13+ years in the industry: live client work you can open right now, our own products, and full web and mobile applications with their source on GitHub. The courses on this site teach the same craft that went into these.

Client work

Live work I've built

Real businesses, real software. Every one of these is live — open them and see for yourself.

Our products

Built and run by us

Our own software, live today. The code stays private, but you can open each one and try it with a demo account.

Open source

Read the code, not just the screenshots

Full applications — web, Android, iOS and the servers behind them — with their source on GitHub and tests running in CI. Clone one and run it yourself.

Dinewise — Restaurant Online Ordering

Dinewise: online ordering, table bookings and a live kitchen screen for a restaurant. Customers order from their phones and pay online or in cash; the kitchen works from a tablet, and every order updates live.

Pulse — Realtime Incident Console

A live incident board shared by every operator: a Ktor WebSocket server, a Next.js web console, and Android and iOS apps from one Kotlin Multiplatform codebase. A dropped connection resumes exactly where it left off.

Stockroom — Inventory and Orders Under Load

Inventory and order-taking that cannot oversell: when twenty people order the last five units at the same moment, exactly five orders succeed. Spring Boot API, Next.js front end, PostgreSQL, one command to run.
