Worked on the IBM/velox repository to enhance both test reliability and hardware support. Addressed cross-version compatibility in the test suite by refactoring LazyCPUThreadPoolExecutorTest, replacing Times-based verification with a manual count to ensure tests pass on older Google Test versions, which reduced CI flakiness and improved onboarding for contributors. Later, implemented Scalable Vector Extension (SVE) support by updating the build system to detect SVE and adding SVE-specific SIMD implementations, enabling 128-bit and 256-bit vectorization on ARM architectures. Utilized C++, build systems, and performance optimization techniques to resolve compilation errors and expand Velox’s hardware compatibility and performance potential.

May 1, 2025May 2025: Stabilized IBM/velox test suite by addressing cross-version compatibility with Google Test. Implemented a test fix for LazyCPUThreadPoolExecutorTest to work with older GTest versions by replacing the Times-based verification with a manual count to validate a prefix, eliminating failures when the Times matcher is unavailable. This work reduces flaky CI failures and improves reliability for contributors.
