I've built and run the backend services and React frontends behind LESMILLS+, LESMILLS Instructor and LESMILLS Content, used by members and instructors worldwide.

01 / About

I'm a software engineer with 6+ years at LesMills International, where I've worked across LESMILLS+, LESMILLS Instructor and LESMILLS Content. I design Node.js and TypeScript microservices, GraphQL and REST APIs and React frontends on AWS, and I take on-call ownership of what I build.

Since 2015 I've also built web apps for small businesses and charities through Nexlogic.
