PROFILE

Will Scullin

During a two-month period, Scullin enhanced the malloydata/malloy repository by implementing timestamptz (timestamp with time zone) support across data rendering and query building features. Using TypeScript and leveraging both backend and full stack development skills, Scullin extended the AST-based query builder and data tree to handle precise time-based analytics, including group by and time truncation. The work included refactoring filter expressions with discriminator-based type handling, unifying timestamp types and reducing edge cases in date/time filtering. These changes improved the accuracy and maintainability of timezone-aware queries, enabling robust analytics on international datasets and strengthening overall data querying quality.
