I build end-to-end mobile and web solutions — from concept and UI/UX design through to production and maintenance. My current focus is React Native and Swift, and beyond my day job I contribute to OS-AID (Open-Source Automated Insulin Delivery) projects that help people manage Type 1 diabetes.
- Building products at Scenius
- Contributing to Trio and Loop — open-source automated insulin delivery systems
