Revanth Pothukuchi developed a Document Deletion API for the onyx-dot-app/onyx repository, focusing on improving ingestion document lifecycle management. He designed and implemented a RESTful DELETE endpoint using Python, FastAPI, and SQLAlchemy, enabling the removal of ingestion documents along with their associated image chunks and related database records. This approach ensured data hygiene by supporting cascading deletions and maintaining database integrity, addressing the need for streamlined retention and compliance workflows. The work demonstrated a solid understanding of backend development principles, commit-driven delivery, and effective cross-team collaboration, resulting in a robust feature that reduces orphaned data and optimizes storage usage.
