Software & Web Developer

I experiment with low-level (sometimes) and I also do fast web prototypes, and self-hosted infrastructure. I care about clean UX, performance, and learning by shipping.

About

Curiosity-driven projects with a focus on performance, UX, and learning in public.

Who am I?

I’m Szymon (SfymmiK), a 16-year-old programmer from Poland. I like experimenting with low-level (C) and also shipping clean, fast web interfaces.

What I enjoy

Building tools I actually use: self-hosting setups, experimental programs, and websites — then polishing the UI until it feels “right”.

Lingustic abilities

I speak both polish and english fluently,
english proficiency level (C1).
