Worked on the modularml/mojo repository to modernize CI/CD workflows and optimize GPU build resources over a two-month period. Focused on integrating remote H100 BuildBuddy-based test execution, fully incorporating tests into presubmit and removing legacy filters and cron jobs. This transition eliminated persistent runners and containers, reducing maintenance overhead and improving feedback speed. Later, reconfigured CI build executors by switching from oci-h100-executors to h100-executors and updating container images for B200 executors, which improved resource utilization and reduced build queue times. Leveraged skills in Build Systems, CI/CD, and Infrastructure Management, using Bazel and Mojo to streamline remote execution processes.
