Worked on the TwentyHQ Twenty repository to deliver type-system enhancements and robust relation-filter fixes that improved both developer experience and runtime reliability. Implemented Currency Field Settings in shared types using TypeScript, allowing currency formats and decimals to be accurately represented in the type system and seamlessly integrated with existing runtime storage. Addressed issues in relation field filter handling by enabling correct matching against related record IDs, which stabilized optimistic UI updates and Row-Level Security permissions. Maintained end-to-end type safety across backend and frontend codebases, leveraging GraphQL and comprehensive testing to ensure improvements were surfaced in the SDK without disrupting existing deployments.
