I cared about building Mercedes-Benz 🛻 Sales software for almost a decade, I'm now integrating data 📄 at ARMEDANGELS 👼 , doing my Masters in Computer Science and planning to use my powers to help the common good 💖 & to protect the environment 🍃.

I like Python, TypeScript, PostgreSQL, Kubernetes and flirt with Rust & AI (of course!) for my next adventures.

Current hobbies are running & strength training, learning vim 🧑‍💻 and transitioning to an eco-friendly lifestyle.

Want me for freelance work? You can contact 📧 me in english, german and you can also try hungarian.

We must all suffer one of two things: the pain of discipline or the pain of regret or disappointment. — Jim Rohn
