Worked on the DayKev/pokerogue repository to enhance data accuracy within the Pokédex by addressing inconsistencies in Dex number displays. Developed a reusable normalization utility in TypeScript to convert species IDs to national Dex numbers, integrating this logic directly into the Pokédex UI. This approach ensured that all Pokémon forms displayed correct Dex numbers, directly resolving a user experience issue and improving data integrity. The work involved refactoring front end components and applying UI/UX design principles to minimize disruption while supporting future feature reliability. Focus remained on bug resolution, with no new features introduced during the period, emphasizing quality and maintainability.
