About me

Dalke.dev

I’m Mateusz. I build realtime Python backends (FastAPI/Django) — fast MVPs and production‑grade systems. I prefer simple architectures, monitoring and quick iterations.

  • Languages: PL 🇵🇱, EN 🇬🇧 — comfortable communication
  • Focus: WebSockets, streaming, Redis/Kafka, integrations
  • Practice: tests, CI/CD and monitoring from day one
  • Collaboration: EU‑friendly, async‑first
