What I do

I'm a Full Stack Software Engineer with a strong backend focus, working mainly with Python (FastAPI) and TypeScript. I build scalable APIs, microservices, and integrations, and I enjoy turning complex requirements into clean, reliable systems.

  • Architecture and development of backend services and REST APIs
  • Real-time systems with WebSockets and event-driven flows
  • External integrations: payments, domains, DNS, SSL, email, wallets
  • Frontend and mobile: React, Next.js, React Native, PWAs, admin dashboards
  • Performance, scalability, and CI/CD with Docker and GitHub Actions
  • Tech lead: code reviews, mentoring, and cross-stack delivery
