During November 2025, Dan Dianass worked on the Amsterdam/mijn-amsterdam-frontend repository, focusing on front end maintenance and migration readiness. He implemented the deprecation of the InfoSection component by renaming it to InfoSection_DEPRECATED across multiple components, establishing a clear migration path and reducing the risk of continued reliance on outdated APIs. Using React and TypeScript, Dan enforced consistent naming conventions and improved codebase maintainability, which will help prevent regressions during future refactors. Although the scope was limited to a single feature, his work addressed technical debt and laid the groundwork for a smoother transition to updated components in the project.
