Worked on the anthropics/beam repository to modernize the development environment by upgrading the dev-support Docker base image from Ubuntu 20.04 to 24.04. This update included refreshing Python tooling such as distlib and yapf to their latest compatible versions, ensuring alignment with current OS security standards and improved build reliability. The work focused on Dockerfile and Shell scripting, demonstrating skills in Docker containerization, Python packaging, and system administration. By maintaining compatibility with the latest Ubuntu release, the changes enhanced the stability of local and CI development workflows, reducing potential build issues and streamlining dependency management for the team.
