Story

how I got here

I started writing code seriously at 18, in a small place where the only path to a real engineering career was self-teaching and shipping things that actually worked. I built tools for myself first — automations, dashboards, extensions — and slowly some of them turned into products other people used.

In 2023 I moved to Germany and joined Devoteam in Frankfurt, doing IT support + internal tooling. In 2025 I joined HASE Kaminofenbau in Trier as a full-stack engineer — they handed me a green field and I built their networked-stove monitoring platform from zero: three UI modes, role-based access, a Monaco-powered scripting terminal, Gemini AI pipelines, the works.

On the side I keep vsdev alive — six Chrome extensions, the Examie EdTech startup for Kazakhstan’s ENT exam, and indie pixel games on itch.io. I like building, I like shipping, and I take work seriously wherever it leads me — including a worldwide relocation.
