About me

# Hello again! I'm Balázs.

I'm a Senior Fullstack & AI Engineer living in Voitsberg, Austria. For 10+ years I've built web applications – from small calculators that help people make better financial decisions to enterprise platforms for global market leaders.

Today AI agents are part of how I build – and I write the tooling that makes them useful in real projects: agent skills that reproduce bugs from real data, fix them and open tested pull requests.

What hasn't changed: I love taking something complicated and making it feel simple – migrating half a million products into a new PIM, untangling a legacy shop until it's fast again, or turning a huge catalogue into a guided configurator. Clean architecture, measurable wins and teams where people help each other grow.

-   ### Kind collaboration

    Clear communication, thoughtful reviews and making sure everyone on the team levels up.
