I build and lead software that has to work where the data can't leave the building.
What I build
LLM search, extraction and assistants running on your own hardware, or routed only through providers you approve. Built features for an LLM-driven OSINT platform and set up model routing restricted to EU, zero-data-retention providers.
2024 – now · EOS Applications
I lead a software team at a Czech defense software company and develop its data platform for electronic warfare and the products around it. 1,400+ commits as top contributor to the platform my team builds.
I also own the release pipeline for customer installs that run fully offline.
What I build with
A web application your analysts or operators use every day, built to last for years rather than weeks. Python and Django: large, long-lived applications with Celery, Channels, PostgreSQL/PostGIS and ClickHouse.
What I fix
A Django or React codebase that slowed down, broke or lost its author. I get it moving again. Three years of migrations, refactors and test coverage on a long-lived production codebase.
It usually comes with awkward data: binary feeds, proprietary exports, old databases. I turn them into clean, queryable data.
How I work
A clear scope, short feedback loops and working software early. You see progress every week, not a surprise at the end.

Part-time through my bachelor's studies, then full-time, on the RHEL Upgrades team. RHCSA and RHCE certified.
2017 · where it started
Some games from the years I was learning. All of them play in your browser.
2020 · Personal blog, 2020–2021
A beginner's series I wrote as a student: compiling, Makefiles, control flow, arrays, strings, structs and memory.
2019 – 2022 · BUT FIT
The degree gave me the software engineering theory I now put into practice.
Thesis: “Adaptive Trading Strategies for Cryptocurrencies”. I built a backtester and a Bitcoin risk metric; the adaptive strategies beat HODL and rebalancing more than threefold under the right conditions.
