I build software and the teams that ship it.

I'm Narongdej Sarnsuwan, nickname O. I run engineering at The Gang Technology in Bangkok, build my own products on the side, and write down what I learn so the next developer doesn't have to start from zero.

It started with a game guild.

At fifteen I wanted a website for my guild, so I learned to make one. I never stopped. I tend to forget what I learn, which is why this site exists: a professional notebook that might help another developer someday.
