Identified and benchmarked critical math and memory functions in the PS5 Toolchain’s libc by comparing them against open-source libraries, creating a clear baseline for game runtime optimization.

Rebuilt and tuned libc math and memory routines in C using SIMD intrinsics and AVX-512, improving memory performance by up to 30% and speeding up key math functions by up to 2× in representative PS5 game workloads.

Designed automated micro-benchmarks and correctness tests (including ULP-level validation) for libc math and memory functions, enabling repeatable performance tracking and safer deployment of optimizations in the PS5 Toolchain.

Collaborated with cross-functional teams to thoroughly test and validate AMD Optimizing CPU Libraries (AOCL), including AOCL-LibM, AOCL-LibMem, and AOCL-RNG

Led the automation of build, test, and deployment processes using Jenkins and Ansible, cutting release time by 50% and decreasing manual effort by 80%

Monitored test results to maintain high-quality standards, reducing bugs by 30%

Benchmarked AOCL libraries against MKL libraries, revealing a 25% performance improvement

Enhanced code quality and test coverage by integrating GNU code coverage tests, achieving a 40% improvement in overall coverage

Participated in code reviews to uphold coding standards and best practices

Effectively communicated within a seven-member team to execute procurement transaction data migration and reconciliation processes

Tested and debugged financial modules to ensure accurate calculations and reporting, decreasing errors by 20%

Created purchase receipts by linking calculations to database as part of Finance and Procurement team
