Over a two-month period, contributed backend features to the OZ-Coding-School/oz_externship_be_03 repository, focusing on study schedule management. Developed and refined a Study Schedule API using Django and Python, implementing CRUD operations with robust validation to prevent scheduling conflicts and ensure data integrity. Refactored the scheduling data model for maintainability, separating core entities and enhancing serializer logic. Introduced date-range filtering to support precise schedule queries and improved API routing for reliability. Comprehensive unit tests were added to safeguard against regressions and support future refactoring. The work emphasized maintainable code, reliable API behavior, and scalable backend architecture for scheduling workflows.
November 2025 – OZ-Coding-School backend (oz_externship_be_03): Focused on scheduling improvements, API reliability, and robust querying to drive product value with a maintainable codebase and faster feature delivery. Key deliverables include modularizing the study group scheduling data model, introducing a CRUD API core with updated routing, and adding date-range querying for schedules. Also fixed API URL routing issues and strengthened test coverage to prevent regressions, enabling safer refactors and scalable growth.
