Worked on the oneapi-src/oneDNN repository to streamline and stabilize AArch64 continuous integration, focusing on unifying build systems and automating nightly validation. Migrated the ACL build to CMake and aligned it with existing CI workflows, reducing fragmentation and enabling faster feedback across architectures. Enhanced CI infrastructure by introducing GitHub-hosted runners, matrix builds, and YAML-based workflow configurations, which improved reliability and maintainability. Addressed maintenance by removing the unused Winograd convolution path for AArch64 CPUs, simplifying the backend and reducing dependency risks. Utilized C++, Shell scripting, and YAML to deliver targeted improvements in build automation, performance engineering, and embedded systems support.

Apr 1, 2025April 2025 monthly summary for oneapi-src/oneDNN: Implemented targeted maintenance to simplify the AArch64 CPU backend by removing the Winograd convolution path. This path was unused by higher-level frameworks and had ACL-related issues, so its removal reduces code complexity, ACL dependency risk, and maintenance burden without impacting end-to-end test performance.

Dec 1, 2024December 2024 monthly summary for oneDNN (repo: oneapi-src/oneDNN). Focused on stabilizing and accelerating AArch64 CI. Delivered unified AArch64 CI by migrating the ACL build to CMake and aligning it with oneDNN CI, creating a streamlined, faster CI path. Added nightly AArch64 build and test runs with scheduled cron jobs and manual triggering to enable end-to-end validation without build caching. These changes reduce CI fragmentation, shorten feedback loops, and improve cross-architecture validation, supporting more reliable nightly validation and faster releases. Technologies demonstrated include CMake-based builds, GitHub workflows, CI automation, and cross-architecture validation.
