Worked on enhancing the Tinfoil feed endpoint within the rommapp/romm repository by focusing on data integrity and reliability. Leveraged Python and Pydantic v2 to validate and sanitize TitleDB entries, ensuring that only clean and consistent data is delivered through the API. Updated the serialization process to utilize the model_dump() method, which streamlined response payloads and reduced the risk of downstream data issues. This work centered on backend development and data validation, resulting in more robust API responses. The approach emphasized enforcing validation and coercion, contributing to improved data quality and maintainability within the project’s backend infrastructure.
