Tomi Mester — data professional, educator and builder. Budapest, Hungary.

$ cat about.md

I've worked in data and IT since 2012 — first inside product companies (Prezi, iZettle), then on my own since 2016 building Data36 into a data science education brand in two languages.

Since 2017 I've taught data science full time: thousands of students, a six-week job simulation course, a 3-month training programme and a members' community. 15+ years of coding and teaching between the two halves.

These days I mostly build — data products, apps and automation — increasingly with AI coding agents rather than around them. Everything below is something I actually shipped and still run.
