Web apps and AI features, engineered to survive production — not just the demo.
I'm a full-stack Next.js engineer for hire. I ship with tests, Docker, CI/CD, and honest progress tracking — and I can prove it: live client sites, public repositories, and a 192-GPU AI inference deployment behind me.
- Live client work
- Bilingual healthcare platform serving patients in Athens
- AI infrastructure
- 24-node / 192-GPU inference cluster deployed & supported
- Open by default
- Public repos, 141 tests, and CI gates you can inspect
I’m Bagtyyar Kovusov. I build the kind of software that’s still maintainable a year after launch — and I work in the open so you never have to take that on faith.
As a solo engineer, I treat shipping speed and production discipline as the same thing: better workflows, sharper tooling, and a pipeline that doesn’t cut corners. You get direct communication with the person writing your code — no account managers, no handoffs.

How I run AI-assisted PRs without shipping slop code
October 4, 2026
AI makes writing code fast. Review is what makes it safe. Here is the gate-based workflow I use on this portfolio so both kinds of code are held to the same standard.

How I work
Every project I ship includes tests, Dockerized environments, CI/CD pipelines, and architecture decisions you can read. I don’t just write code — I build systems that stay maintainable after I hand them off.
