ABOUT ME
15+ year web development veteran. Haven't seen a problem I can't solve.
15+ year web development veteran. Haven't seen a problem I can't solve.

15 year veteran of the web development world. Worked with hot startups and Nokia amongst other things, and I'm still excited about programming so I also write about it on my site.

I like interesting languages like Haskell or Prolog, but nothing beats JavaScript when you want to get things done. When I'm not programming or playing games, you can usually find me on IRC helping people solve all their most difficult programming problems.

I've used JavaScript a lot: Frontend in the browser, NodeJS backend stuff, MongoDB, JScript automation scripts, even app development on the now-defunct Palm webOS mobile phone OS. I've built a number of games with it, including what I'm reasonably sure was one of the first browser-based realtime online games.

I put high value on using unit tests (and integration tests etc.) to verify program behavior. They are very useful especially in large-scale apps and during development to make sure new changes do not cause bugs in old code.
