PROFILE

Peizhang56

Worked on jeejeelee/vllm and ROCm/rccl, focusing on backend reliability and robust testing for AMD ROCm environments. Developed comprehensive unit tests in C++ for bit manipulation utilities in bitops.h, improving validation and reducing regression risk. Enhanced CI/CD pipelines using Buildkite and YAML, expanded hardware coverage, and stabilized memory management for large-model evaluation. Addressed test flakiness by isolating test execution, refining memory teardown, and introducing utilities for memory profiling and settlement. Improved test infrastructure by updating dependencies and packaging, while also resolving issues with HIP context safety and FP8 decode paths. Emphasized code review, software testing, and continuous integration throughout.
