Developed a performance-focused feature for the NixOS/nix repository, introducing multi-frame Zstd compression to enable parallel decoding and improve decompression throughput. Leveraging C++ and expertise in compression algorithms and parallel processing, the work implemented frame-based encoding with frames every 16 MiB, allowing independent decoding and reducing memory usage during compression. The approach maintained full compatibility with existing tooling, including libarchive and the zstd CLI, by ensuring mandatory frame concatenation and adherence to RFC 8878 framing requirements. This feature reduced peak memory consumption and established a foundation for future multi-core enhancements across the Nix store, demonstrating strong system programming skills.
