Software Engineer & Hardware Enthusiast

First-year Software Engineering student at SPbGETU (LETI). My real interest is in the hardware–software boundary: bare-metal embedded development, low-level systems programming, and building infrastructure from scratch.

I write C, C++, Rust, and Java, debug things most people walk away from, and run a self-hosted homelab that has taught me more than any tutorial. I actually enjoy reading datasheets and reference manuals.
