Summary

Rockstar🎓
Top SchoolSzymon Mentel is an Elixir engineer with 12 years of experience building and operating resilient distributed systems, currently contributing to Supavisor’s PostgreSQL connection pooler at Supabase. He brings deep expertise in Erlang/Elixir, RabbitMQ and global clustering, and has led teams and consulted on high-scale messaging and load-testing projects. Szymon has a strong AI/ML tooling pedigree—building Docker Swarm infrastructures for model management, optimizing pgvector-backed embedding tables, and shipping a LangChain/Python assistant for semiconductor maintenance. He’s equally comfortable in developer-facing roles, having created and demoed LLM-based personal assistants and sample apps while in DevRel at Fly.io. Beyond code, he’s an active mentor and operator who turns research prototypes into production services and quietly battles memory leaks and performance bottlenecks. Based in Krakow, he balances engineering with adventurous hobbies like bike travel and mountaineering, which inform his pragmatic, endurance-oriented approach to long-running systems.
