Worked on backend data engineering for the opendatahub-io/feast and red-hat-data-services/feast repositories, focusing on enhancing Trino integration and data interoperability. Built a Lakehouse Trino Offline Store Connector, enabling reliable offline analytics by improving timestamp handling and SQL query consistency. Addressed cross-environment compatibility by refining date-type mappings between Trino and Feast, ensuring downstream data consumption remained accurate. Resolved a Pydantic deprecation warning to maintain compatibility with evolving Python libraries. Leveraged Python, SQL, and Feast to deliver robust features and targeted bug fixes, demonstrating a methodical approach to backend development and a focus on production stability and maintainability across data platforms.
