Jakub Konka is a systems programmer with 13 years of experience, based in Warsaw, who contributes to core Zig language development and works on the Zed editor. He blends low-level systems work—WASI host call and process primitive implementations in Wasmtime—with practical front-end contributions to projects like Microsoft Fluent UI, demonstrating a full-stack fluency uncommon in systems engineers. Jakub has deep cross-platform and build-system knowledge shown by infrastructure and release work for ziglang.org, including MachO linker and macOS release packaging. A PhD-level engineer trained at the University of Strathclyde, he pairs rigorous academic grounding with hands-on open-source impact. Colleagues value him as a problem solver and open-source enthusiast who moves between Rust, Zig, and JavaScript ecosystems to improve performance, security, and developer UX.
