  • Strong proficiency in Python and experience with FastAPI or similar frameworks (Flask, Django).
  • Solid hands‑on experience with Angular (2+) and TypeScript, including RxJS and component‑based architecture.
  • Comfort working with relational databases (MySQL or PostgreSQL), writing efficient queries, and managing schema changes.
  • Experience with REST APIs, Git‑based workflows, Docker, and CI/CD tooling; familiarity with GraphQL is a plus.


Perks and benefits:

  • Comprehensive benefits - enjoy Udemy for Business, private medical care, Multisport card, veterinary package, language lessons, and shopping vouchers.
