During October 2025, Tuan Le Anh focused on backend stability for the srbhr/Resume-Matcher repository, addressing a critical dependency conflict between Starlette and FastAPI. Using Python and leveraging backend development and dependency management skills, Tuan resolved version mismatches that previously risked runtime errors, updating the pyproject.toml to ensure reliable integration of both libraries. No new user-facing features were released, as the primary goal was to improve maintainability and reduce production risk. Tuan also documented the changes to support future upgrades, laying a solid foundation for upcoming feature work by stabilizing the core backend stack and simplifying future dependency updates.
