About me

Full-stack developer with a background in cyber security — I build web applications end to end, from the database to the interface.

I hold a Bachelor’s degree in Applied Informatics from the Slovak University of Technology in Bratislava and a Master’s degree (Ing.) in Cyber Security from Brno University of Technology. I’ve been building software professionally since 2021 — first at a software company in Bratislava, then on projects for Czech national security authorities, and since 2023 as a full-stack developer at Helikar Lab, working on the Cell Collective research platform.

I like to move forward quickly, take responsibility for the result and think problems through analytically. Outside client work I build my own tools — like FlatWatch, a self-hosted apartment watcher for Bratislava.

How I work

What you can expect when we work together.

  1. Clear scope first

    We agree on what “done” means before any code is written.

  2. Small, reviewable steps

    Work arrives in pieces you can test, not in one big drop at the end.

  3. Regular updates

    You always know what is finished, what is next and what is blocked.

  4. Clean handover

    Readable code and short notes, so your team can continue without me.
