Senior🎓
Top SchoolŁukasz Mikołajczak is an Expert Backend Engineer and Tech Lead based in Amsterdam with 11 years of experience building scalable services using Python, Go, and BEAM languages (Elixir/Erlang). He has progressed from GIS-focused Python development to leading backend teams at Typeform, combining domain knowledge in geographic information systems with production-grade backend engineering. Known for mentoring juniors and contributing to open-source (github.com/lmikolajczak), he blends hands-on coding with leadership in distributed systems and reliability. His stack fluency enables him to choose pragmatic tools for performance-sensitive workloads and long-lived services. A subtle strength is his GIS background, which informs thoughtful data modeling and spatial-aware system design not obvious from a typical backend résumé. He is open to collaboration and consistently seeks to translate complex requirements into maintainable, testable systems.
