About

I build software, start companies, train, and like looking at numbers. I do not live these as separate lives but as faces of the same curiosity: try something, measure it, write down what happened.

This site is the open version of that record. I keep it for myself first, to remember months later why I did what I did. Then for people walking similar roads: not a recipe, the real process.

Nothing is for sale here. If you have an idea, a question or an objection, e-mail is the best way: rberkkaratas@gmail.com.
