About me

I can help companies build maintainable web applications and performant websites that convert visitors into customers. I currently live in Asia and specialize in web application and product development with React. For personal projects I work across the full stack with Flow, MobX, Node.js and Docker, including server administration. Besides tech I'm really into travelling and photography.
