About
Engineering that ships — and scales.
I'm a senior mobile engineer with 6+ years building production apps for iOS and Android. I specialise in Flutter and Dart, but I work end to end — React and Next.js web front-ends, Node.js, Go and .NET backends, AWS infrastructure, CI/CD, and increasingly AI and LLM integration.
I've taken a fintech from solo MVP to a scaling team (Nagro), engineered a mobility super-app for 1M+ users (Mottu), and rebuilt established apps from native to Flutter without missing a beat (IngressoLive). I care about clean architecture, performance under real-world load, and products people actually keep using.
