Hey, I'mJaakko.
A 17-year-old full-stack developer from Finland who started coding at 12 and never stopped. I build real products used by real people — and I'm just getting started.

Full-Stack Developer · 17
I wrote my first line of code at 12 — a clunky HTML game for my friends. The moment I saw it run in a browser, I was hooked. That feeling of turning nothing into something interactive has driven everything since.
At 17 I'm a freelance full-stack developer working with Finnish companies like Tutors Finland OY, building platforms used by thousands of students. I've shipped marketplaces, AI tools, SaaS dashboards, and real-time chat apps — all while still in school.
I believe great software isn't just about clever code. It's about understanding the person on the other side of the screen, iterating fast, and never shipping something you wouldn't be proud of.
