About Me

I’m a freelance (web)developer with over 22 years of experience. My parents bought me a C64 at age 7 and I’ve been coding non-stop since then. 

I’m specialised in backend /app development and designing large scale SQL databases.

For the past 3 years I’ve been active in developing algorithmic trading systems.
