PROFILE
Yanghan Wang
Yang Han enhanced the CI/CD infrastructure for the facebookresearch/detectron2 repository, focusing on build reliability and maintainability. Over three months, Yang updated GitHub Actions workflows using Python and YAML to optimize dependency management, environment caching, and evaluation script execution, which improved reproducibility and accelerated pull request validation. Yang addressed Windows-specific CI issues by disabling a non-functional dependency cache, stabilizing builds and simplifying debugging. Additionally, Yang overhauled the CI setup to ensure compatibility with the latest PyTorch and CUDA versions, revising installation scripts to reduce flaky builds. The work demonstrated depth in DevOps, continuous integration, and cross-platform environment management.
