Erik Haider Forsén enhanced the CI/CD infrastructure for the code-obos/grunnmuren repository by implementing a workflow that triggers main branch builds on all changes, improving coverage and reducing manual misconfigurations. He utilized GitHub Actions and YAML to ensure that both push and pull request events consistently initiated the CI pipeline, closing feedback gaps and strengthening release readiness. Additionally, Erik stabilized the build environment by pinning the Docker base image to version 1.0.2, resolving Corepack-related failures and ensuring deterministic, reproducible builds. His work focused on containerization and DevOps practices, delivering targeted improvements over a two-month period.
