PROFILE
Keshav Kolur
Worked on modernizing build systems and cross-platform dependency management across several Facebook repositories, including buck2, sapling, folly, and ocamlrep. Delivered features such as migrating OS-dependent dependencies to Buck select() patterns, simplifying OSS shim layers, and aligning architecture-specific flags for improved maintainability and platform compatibility. In facebook/buck2-prelude, enabled cache uploads for locally run jar actions to the CI cache, reducing cold-build times and improving build performance. Also migrated Thrift imports in facebook/fbthrift to the Autodeps2 Python structure, enhancing compatibility and maintainability. Utilized C++, Python, and Rust, focusing on build system configuration, CI/CD integration, and performance optimization.
