// 04 — about me
3 years in back-end — and most of that time I've been deep in legacy code. I know how it goes: wrapping your head around someone else's architecture, fixing bugs in systems with zero documentation, keeping it all running. I've got the skills for it, but honestly — I want more than that.
I want to build things from scratch, think through the architecture myself instead of adapting to whatever already exists. I want to work with modern tech in a team where there's room to grow and people actually care about what they're building.
Actively looking for a remote position. Studying Computer Science at VNTU while working full-time — I'm used to the pace. Fluent in Ukrainian, solid English (Upper-Intermediate).

Actively looking for a remote back-end role. I've got legacy experience and I'm ready to build something new — if you've got an interesting project, let's talk.
