Worked on the aws/aws-lc repository to deliver performance enhancements for RSA cryptographic operations on Windows, focusing on enabling IFMA (Intel AVX-512 Integer Fused Multiply-Add) acceleration. Used C++ to update CPU capability checks, ensuring proper recognition of IFMA support and optimizing low-level memory allocation for test reliability. Addressed platform parity by improving Windows-specific crypto performance and fixing the RSAZABI test through targeted changes in the test harness. Emphasized cryptography, low-level optimization, and Windows development skills to strengthen cross-platform consistency, accelerate cryptographic workloads, and enhance test coverage, contributing to faster deployment readiness and more robust cryptographic functionality.
