During the month, contributed to the Opetushallitus/aoe repository by simplifying the GitLab CI pipeline, focusing on improving reliability and maintainability. The work involved removing the Docker-in-Docker (docker:dind) service and eliminating before_script checks for Docker and Docker Compose versions, which streamlined the continuous integration process. This change reduced pipeline complexity and led to faster CI feedback cycles, minimizing unnecessary churn during development. The implementation relied on skills in CI/CD and Docker, with YAML used for configuration. No bugs were addressed during this period, and the primary deliverable was a single feature aimed at optimizing the project's CI workflow.
