Artur Kisiolek
CTO at Artificial Labs
England, United Kingdom
Summary
🤩
RockstarArtur Kisiolek is a CTO with 18 years of hands-on engineering and leadership experience, based in England, UK. He combines deep functional-programming expertise with production-grade backend engineering, evidenced by significant contributions to prominent Haskell projects like Stack, Stackage, Intero and the Fay-to-JavaScript compiler. At Artificial Labs since 2014 he has blended strategic tech leadership with low-level compiler and tooling work, including integrating BigQuery support into Hasura’s GraphQL engine. Artur’s strengths lie in turning complex language and dependency problems into robust developer tooling and reliable build systems. He is comfortable navigating both product-level architecture and the nitty-gritty of parsers, serializers and REPL/CLI ergonomics. That rare mix of CTO-level strategy and compiler/compiler-adjacent craftsmanship makes him a strong fit for teams building developer platforms or data-centric backends.
