Worked on the OZ-Coding-School/oz_externship_be_03 repository, delivering backend features such as lecture bookmarking and a scalable recommendation system. Built robust API endpoints and integrated pagination, user assignment, and Redis-based caching to improve performance and user experience. Refactored the ALS recommendation engine for stability, incremental learning, and query optimization, while expanding integration and unit test coverage using Python, Django, and NumPy. Enhanced code quality through formatting, dependency management with Poetry, and CI reliability improvements. Addressed bugs in matrix operations, caching, and URL handling, ensuring maintainable, well-documented code that supports data correctness, usability, and efficient backend operations at scale.
