Worked on the secretflow/spu repository, delivering core features and improvements in secure multi-party computation and distributed systems. Developed robust kernel-level cryptographic operations in C++ and Python, enhancing the reliability of permutation, sorting, and SOPRF functions. Advanced the messaging framework by implementing an HTTP-based channel for asynchronous inter-node communication, complete with pybind bindings and comprehensive tests. Focused on build management using Bazel and version control, streamlining release processes through precise versioning and configuration updates. The work emphasized correctness, maintainability, and scalability, addressing both cryptographic protocol robustness and the reproducibility of development builds in a collaborative, production-oriented environment.

May 1, 2025May 2025 performance summary for secretflow/spu focusing on release management and build traceability. Delivered development versioning and release tracking by updating version numbers across multiple configuration and header files to reflect a new dev build 0.9.4.dev20250522, enabling precise dev-build identification and streamlined release management. This work was validated by commit 26c23f101f038e248e6c258f9f6971a49a3e4374 ("bump version to 0.9.4.dev20250522 (#1146)"). No major user-facing bugs fixed this month; the emphasis was on stabilizing the dev-build process and improving release management. Overall impact includes improved reproducibility of dev builds, clearer release tracking, and stronger CI/CD readiness. Technologies/skills demonstrated include version control discipline, multi-file configuration updates, and release-management practices.
