Rockstar🎓
Top SchoolKamil Kisiela is a software developer based in Warsaw with 11 years of experience building full-stack web applications and developer tooling. He has a strong focus on GraphQL—contributing to high-profile projects like Apollo Client, Graph Node, GraphQL Mesh and GraphQL Inspector—working across schema design, execution, plugins and performance optimizations. Equally comfortable on front-end Angular/React integrations and back-end services, he has shipped features from client-side caching and query APIs to server-side validation, metrics and API versioning. His open-source work shows attention to robustness (memory-leak fixes, caching validation) and backwards compatibility across ecosystems. At The Guild Software and Jelly JS he continues to shape GraphQL developer experiences and tooling while also maintaining hands-on delivery for production systems. An understated strength is his knack for bridging developer UX with deep execution-layer improvements, improving both DX and runtime reliability.
