Developed a Generic Landmark Class transformation for the Hivemapper/odc-api repository, enabling plugin consumers to interact with a unified landmark data interface. The work involved designing and implementing robust transformation logic in TypeScript to convert specific landmark types into a generic class, ensuring consistent application across multiple API routes. This approach improved interoperability and data consistency for downstream plugins, reducing the need for client-side data manipulation. The feature was delivered with strong Git-based traceability, linking requirements directly to code changes. Core skills applied included API development, backend engineering, and TypeScript, with a focus on maintainable, cross-route data transformation solutions.
