Worked on the openstad-headless repository to enhance build reliability and continuous integration performance by optimizing Docker build cache management. Focused on enforcing a fresh npm cache during Docker image builds, this approach reduced the risk of stale dependencies affecting package installations and improved overall reproducibility. The technical solution involved modifying the Dockerfile to force npm cache cleaning, which led to faster and more predictable CI runs while minimizing build failures related to cache hygiene. Leveraged skills in build automation, DevOps, and Dockerfile scripting to deliver a targeted feature that improved deployment pipeline stability without introducing new bug fixes during the period.
