ABOUT ME

Coding addict since age 10 I now master many things

Currently Javascript is my dope, both in the browser and using NodeJS. I know many protocols, patterns, coding styles, operating environments and languages.

I have partaken in multiple company startups, small and larger mobile device app development projects, and worked for many different size companies, including Ericsson, ManagerZone, City Network, GlobalFun, AllBinary and several others.

I can certainly be of help in getting you closer to solving your problem. My vast experience and information gathering skills is a great resource to have at hand!
