I'm currently building and maintaining core C/C++ components for Oracle GoldenGate, supporting production replication workloads and database-side compatibility across releases.

At Intel, I built cross-platform C++ validation tooling for Power Management and Reset, led a UEFI application for PCIe Physical Layer validation, and automated regression testing with GitHub Actions, cutting manual validation time by approximately 30%.

My background also includes CXL post-silicon validation, Linux-based stress-testing tools, and embedded medical monitoring devices using Embedded C, RTOS, Wi-Fi, and MQTT. I enjoy improving development workflows through test design, automation, and AI coding assistants.
