About me

Stuffmatic is a name that I, Per Gantelius, call myself when creating stuff for money and for fun. I'm a freelance developer working in a fairly wide range of fields; frontend, backend and beyond - high level, low level or anything in between.

My background is in computational mathematics, sound engineering and game development and I enjoy achieving beauty through nerdy means. Real time audio and 3D graphics are among my specialties. I'm a nerd (obviously) but I also care about aesthetics. And I like stuff that works.

I live in Stockholm, Sweden and I'm always on the lookout for interesting projects and nice people doing cool stuff. Are you looking for a developer? Or just want to get nerdy over a cup of coffee? Don't hesitate to drop me a line!
