PROFILE

Doug Kwan

Worked on the google/silifuzz and google/fuzztest repositories, delivering features that enhanced cross-platform traceability, platform support, and build system robustness. Developed cross-platform snapshot tracing and improved snapshot test reliability using C++ and Python, while also modernizing dependency management through Bazel. Expanded platform coverage by adding AMD Venice support and improved user accessibility by updating build visibility for public features. Contributed to code quality by refactoring random number generation into a reusable library and increasing test coverage for EVEX prefix persistence. Addressed external execution robustness in fuzz testing workflows, demonstrating strengths in system programming, automation, and architecture-aware design across multiple environments.
