Summary
👤
Senior🎓
Top SchoolKamil Kowalski is a Staff Engineer with 11 years of experience, currently leading Fresha’s architectural transformation as the company scales globally. He combines hands-on Elixir, Ruby and JavaScript development with systems-level thinking—having driven a migration from a Rails monolith to independent Ruby- and Elixir-based services and React front-ends. Formerly an engineering manager and technical lead, he pairs technical delivery with coaching, recruitment and cross-team coordination to shorten feedback loops and improve throughput. Based in Warsaw, he brings a practical blend of backend performance optimization, API design and observability work, and unusually for a staff engineer, a persistent interest in IoT and consumer-facing tinkering. Outside work he’s known to debug hardware as readily as code, and he apparently makes excellent pancakes.
