About me

I can help companies build and launch maintainable web applications and performant websites, that convert visitors into customers, in a transparent and clearly communicated way. I currently live in Bangkok and specialize in web application and product development with React (5 years). For my own projects I work across the full stack with Node.js. Besides tech I'm really into travelling and photography.
