Worked on the code-obos/grunnmuren repository to enhance CI/CD reliability and build stability over a two-month period. Improved the GitHub Actions workflow by configuring main.yml to trigger on all changes, ensuring comprehensive CI coverage for both push and pull request events and eliminating path-based exclusions. Addressed build instability by pinning the Docker base image to version 1.0.2, resolving Corepack-related failures and enabling deterministic, reproducible builds. Utilized Dockerfile, YAML, and DevOps practices to streamline the release process, reduce manual misconfigurations, and accelerate integration cycles, resulting in a more robust and predictable CI/build environment for the project.
