During June 2025, Zeyi focused on hardening the build systems for the fbthrift and CacheLib repositories by improving how Python DLLs are discovered within CMake configurations. Zeyi removed hardcoded search paths, replacing them with a more robust and environment-agnostic discovery mechanism. This approach reduced build fragility and improved consistency across continuous integration environments. Working primarily with C and CMake, Zeyi’s changes streamlined the build process, making it less dependent on specific system configurations and easier to maintain. The work addressed both a feature and a bug, resulting in faster onboarding for new developers and more reliable cross-repository builds.
