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
