Oct 1, 2025October 2025 focused on stabilizing CI/CD for Artemis. Delivered a targeted bug fix in Build Agent SSH URL generation: removed the '/scm' prefix from repository paths, ensuring the build agents can clone repos via SSH. The change was implemented in ls1intum/Artemis and committed as 7c932aa9d97cdd2f0091e7e767194ff815986757. This reduces SSH clone errors, decreases build flakiness, and accelerates release cycles, delivering tangible business value through more reliable pipelines and faster feedback for developers. Demonstrated skills include debugging, Git commit hygiene, SSH-based Git operations, and CI/CD reliability engineering.
