Lucy Wang developed a Media Transformation API for the palantir/osdk-ts repository, enabling image resizing, video transcoding, and audio transcription across diverse media types. She designed the API with a focus on scalable architecture and type safety, leveraging TypeScript for robust type definitions and future extensibility. Her work included updating type surfaces, exporting new types, and resolving build and dependency issues to ensure a stable experimental rollout. By addressing cross-media processing needs and aligning with business requirements, Lucy established a technical foundation for advanced media workflows, demonstrating depth in API development, media processing, and TypeScript-based software engineering practices.
