Worked on the hmcts/rd-caseworker-ref-api repository to deliver new skill data supporting CCMC/CMC Management and Multi Track Trial Management. This involved updating the SKILL table in the database to include new service IDs and ensuring that all related functional tests accurately reflected these changes. Using Java and SQL, the developer focused on backend development and database management, making clean, traceable commits that maintained the integrity of the data layer. All updates were validated through continuous integration and functional testing, with no regressions detected, demonstrating careful attention to quality and alignment with existing features during the month-long development period.
