Worked on the facebookresearch/faiss repository to enhance code cleanliness and long-term maintainability by removing deprecated RAFT headers. This effort involved identifying and eliminating outdated dependencies, aligning the codebase with upstream RAFT deprecations to minimize future build-time warnings and reduce maintenance overhead. The changes were consolidated into a single, well-documented update, ensuring traceability and facilitating safer future cleanups. The work focused on C++ development and GPU programming, with an emphasis on software maintenance practices. No bugs were fixed during this period, but the feature improved the overall structure and reliability of the codebase for ongoing and future development.
