- 2023 to 2026
- BSc Computer Science, MFF UK; thesis graded Excellent
I started programming as a teenager. After secondary school in Mladá Boleslav I spent a year studying pharmaceutical synthesis at the University of Chemistry and Technology in Prague, then switched to computer science at Charles University and specialized in systems programming.
Alongside school I started building AI products with Lukáš Hellesch, who later became my co-founder at Zoplio. One of them was Boletiqo, a platform of agent teams meant to run a small company, which made the Czech national top 10 of Red Bull Basement ’26. Watching those agents confidently misreport their own results is what made me curious about what goes on inside the models. In January 2026 I joined Kreedl as an AI engineer and built an internal Gemini pipeline for pitch-deck analysis. In March, next to that job, Lukáš and I started Zoplio, an AI assistant that books meetings, and I wrote all of its backend. In October 2026 we put Zoplio on hold: on its own, it was a feature rather than a standalone product. Since then I send fixes to open-source projects, such as PostHog’s JavaScript SDK, and I keep going to hackathons (the list).
02
What I’m looking for
An AI or backend engineering role. I’m happiest on the systems other engineers build on, and I like being the person they can ask. The details (where, when, what kind of contract) are on the Now page.
03
Research
Alongside engineering I look inside neural networks: how a network carries a concept, and how a model uses its KV cache over a long context. Four projects so far: three done or written up, one still running, all on the research page.
On the side I run GazeUp, daily AI news in Czech as short videos and a weekly newsletter.
