About

I am originally from Prague, Czech Republic and now based in Berlin, Germany. I have worked across enterprise and startup teams, helping products scale from early systems to production-critical platforms.
With 25+ years of engineering experience, I focus on distributed systems, reliability, and pragmatic delivery. I also contribute to open source and regularly share practical lessons from real-world systems work.
What I work on
- Distributed systems design and production reliability
- Performance tuning for APIs and backend services
- Cloud-native platform engineering and operations
- LLM/AI integration into real team workflows
- Technical leadership, mentoring, and delivery
Core technologies: Erlang/OTP, Elixir, Go, TypeScript, Python, PostgreSQL, AWS, REST APIs, distributed systems
