Pavlo Koval
Product engineer in Berlin.
I build products end to end: the interface, the system behind it, and the part that has to keep working after everyone goes to sleep.
Work
- FastFrame 2026 to now
- Founding engineer since October 2026. You describe the ad you need, and an AI assistant builds and runs the workflow that produces it.
- HolyWater 2025 to 2026
- Tech lead of the platform that turns drama episodes into hundreds of video ads a day.
- Maprehend 2023 to 2025
- Product engineer and frontend lead on instant quoting for sheet-metal manufacturers and solar installers.
- Techmagic 2022 to 2023
- Software developer on web microservices and a search API.
Things I built
-
Solar system
Every planet where it really was, and a black hole for a cursor.
-
Audiobook player
Offline, in the browser, no server.
-
jingo
Pictures sent as sound, the way radio amateurs do it.
-
Drus-Ja
My own programming language. Write something in it here.
Earlier, to see how things work: SHA-256, RSA and a CISC simulator from scratch in C++.
How I work
- I plant violations in my own checks to prove they work. Four of them didn't.
- I run AI agents like a team. One reviewer outranks the coders, and nothing ships without a yes.
Background
Computer Engineering at Lviv Polytechnic. I speak Ukrainian and English. My German is A1, and improving.
