I'm Mário, a full-stack developer based in Slovakia, currently studying in Brno.

I've grown to love building things with C#, Python, and Rust, and I enjoy designing projects with clean, scalable architecture.

When I'm not coding, I'm probably doing some sports, gaming, or watching something from my IMDB watchlist.

I love getting better at what I do — there's a real joy in tackling something that seemed daunting at first and realizing it's not as hard as it looked. I'm always hunting for new perspectives, tools, and tricks. I also really enjoy helping people and seeing how others approach the same problems differently than I would.
