03about

3.1 in short

I'm Mico, a developer from Finland. Coding started as a hobby and still is one. I've done a lot of web work, but backends excite me the most: APIs, databases, and things that keep working reliably year after year.

Many of my projects were built for communities I spend my own time in, like the 350+ member Tectonic clan. Real users and their feedback have taught me more than any course.

When I'm not coding, I go running, work out at home, or play the same games I build tools around.
