Worked on the EMMC-ASBL/tripper repository to deliver a SPARQLwrapper backend supporting end-to-end SPARQL query execution, enabling robust data retrieval from SPARQL endpoints. Focused on backend development and API integration using Python, with an emphasis on code quality and maintainability. Enhanced the test suite to improve reliability, including language consistency and import management, and refactored code to align with Python conventions by reorganizing module imports. No major bugs were addressed, as the work prioritized new feature delivery and long-term maintainability. The approach demonstrated attention to code organization, testing, and refactoring, laying groundwork for future enhancements and easier code review.
