Worked on oraichain/OpenHands and ansys/pymapdl, focusing on CI/CD, DevOps, and Docker. Delivered a feature for OpenHands by introducing an LLM_API_VERSION input to the resolver workflow, enabling explicit API version pinning for resolver jobs. This approach improved system stability, reproducibility, and auditability by standardizing version-controlled configuration using YAML and Dockerfile. In ansys/pymapdl, addressed a documentation bug by clarifying Docker build instructions, including path arguments and enforcing lowercase TAG variables, which aligned the documentation with the actual CI workflow. These contributions enhanced onboarding, reduced support issues, and ensured more reliable build processes through precise documentation and workflow improvements.
