About Me

Hey, I'm Kuba — online I go by pxseu. I'm 21 years old and have been writing code for 7 years. I care about building systems that don't fall apart: clean, maintainable, and structured in a way that actually makes sense.
My thing is backend systems and internal tools — the kind of work that's rarely flashy, but absolutely essential. I like clarity, reliability, and the feeling of leaving something better than I found it. If it can last years without turning into a mess, I've done my job right.
I'm naturally curious — sometimes annoyingly so. I end up in weird internet corners, digging into obscure protocols, vintage tech, or whatever random detail catches my brain that week. I don't chase trends much; I just follow the "wait, that's interesting" moments wherever they go.
Outside of code, I'm into cars and overly specific gadgets that serve one purpose perfectly. I like things that are well-built, well-designed, and a little bit unnecessary — but in a good way.
Every now and then, I also dabble in content creation — making videos, sharing projects, or documenting random experiments. It's a fun creative outlet and a good way to stay inspired outside of the usual routine.
I don't pretend to have it all figured out. I build, I break things, I adjust. That process — of iterating until something feels right — is where I do my best work.
