Worked on the navikt/aap-oppgave repository to enhance development environment hygiene by cleaning up outdated frontend application references in the .nais/app-dev.yaml configuration file. Focused on configuration management and DevOps practices, the work involved safely removing deprecated app definitions to streamline the setup process and reduce confusion for developers. Using YAML as the primary language, the changes consolidated environment references, minimized the risk of misconfiguration, and contributed to a more maintainable and predictable development environment. This targeted update supported faster onboarding and improved overall configuration clarity, delivering measurable value through a single, well-scoped feature without introducing new bugs.
