FAQ

straight answers

Are you available right now?

Day job at HASE Kaminofenbau (Trier, DE). Open to freelance/contract on the side and to full-time offers that beat the day job — including international relocation.

Where can you relocate?

Anywhere with a path to a work visa. Kazakhstan passport + currently on a German residence permit. I've already moved once, I can move again.

Do you take agency / white-label work?

Yes — if scope is concrete and the contact stays direct between me and the technical lead.

Will you do crypto / gambling / adult / casino projects?

Open to discuss — every brief is its own conversation. The code matters; legality and ethics are filtered case-by-case.

Rates?

Depends on scope. Small one-week MV3 fixes start lower, multi-month full-stack projects are quoted per milestone. Hop on a 30-min call and I'll send a number same day.
