Worked on the Tietokilta/web repository to deliver targeted improvements in content management and data integrity. Enabled H4 headings in Payload CMS by modifying its configuration, expanding editorial flexibility for content authors. Later, implemented an automated revalidation mechanism for the honors collections, ensuring that awarded-honors and honors data remained consistent after updates and supporting reliable downstream analytics. Both features were delivered through focused, traceable commits, emphasizing maintainability and reviewability. The work leveraged TypeScript and full stack web development skills, with a focus on CMS configuration and data reliability, addressing specific workflow needs without introducing unnecessary complexity or changes outside the defined scope.
