Worked on the instabase/aihub-openapi repository to deliver two targeted API enhancements over two months, focusing on document processing flexibility and digitization speed. Enhanced the OpenAPI schema and documentation using YAML to introduce optional parameters for entity detection and image handling, clarifying defaults for easier integration. Later, developed a Fast Mode API feature that accelerates digitization by bypassing select preprocessing steps, with enforced dependency constraints to ensure correct flag usage. All changes were iteratively refined through a rigorous code review process, emphasizing API design, documentation clarity, and OpenAPI Specification best practices to improve developer experience and reduce integration risk.
