Pet management, business management and social networking platform, shipped as a PWA and as a React Native app.
The data model came first: a PostgreSQL schema on Supabase that had to hold pets, allied businesses and a social feed without turning into three separate products. The backend started on Firebase and I moved all of it to Supabase. The app shipped as a PWA until that stopped being enough, and then became a React Native app with Expo.
Event management and ticketing platform with dynamic ticket generation, automated email delivery and payment gateway integration.
A ticketing platform for a real venue, which meant the interesting part was never the interface: tickets are generated on the fly, mail goes out on its own and money changes hands through a payment gateway. I built the Angular frontend and the REST API behind it, covering authentication, events and galleries.
