Worked on the mastodon/joinmastodon repository to address data integrity issues following a server migration, focusing on post-migration hygiene for testimonial content. Applied front end development skills and TypeScript to implement a targeted fix that updated testimonial data, specifically correcting a broken link and username to reflect the new server environment at gardenstate.social. The approach ensured accurate user references and reliable links, reducing potential confusion for end users and minimizing support needs. All changes were documented with clear commit history for traceability, aligning with broader migration efforts and maintaining consistency across user-facing data after the legacy domain ceased forwarding.
