During April 2026, contributed to the google/XNNPACK repository by enhancing cross-platform build and testing infrastructure, focusing on improving CI reliability and reducing build times. Leveraged C, C++, and Python to upgrade build systems and streamline performance by removing unnecessary code annotations, which improved code safety and maintainability. Developed and introduced new f16-vmulcaddc microkernel implementations targeting RISC-V architecture, resulting in increased floating-point throughput for machine learning workloads on embedded systems. The work demonstrated a strong command of low-level programming, build system configuration, and performance optimization, addressing both infrastructure robustness and computational efficiency within a single development cycle.
