Technical & data feasibility

I started my first web development company in 1998 in Poland after 3 years of creating websites only for fun.

I have created jsFiddle - a leading site to present HTML5 examples.

I am employed as Web Developer at Mozilla. I am working on Add-on Builder and some other smaller projects.
