HTL St. Pölten · Electronics & Computer Engineering

I build things
that work.

I'm Kilian, a student in my final year at HTL St. Pölten. I like building things you can touch: circuits, boards, firmware — and the occasional web app to control them.

About me

Electronics isn't just a school subject to me — it's what I do after school, too.

It started with tinkering and broken devices; today I build complete projects: from the 4-layer PCB in Altium and the ESP32 firmware to the web interface that controls everything. In between: robotics with the Botball team, the volunteer fire service, and more ideas than time.

I like solutions that are simple and robust — few components, hand-solderable, and when in doubt, measure once instead of guessing three times.
