PROFILE

Arthur Loiselle

Worked on the dialoguemd/fastapi-sqla repository to enhance backend testing and maintainability. Developed startup-integrated pytest fixtures for both synchronous and asynchronous database tests, refactoring session and engine management to align with FastAPI’s startup lifecycle. This approach ensured reliable database connections and robust session rollback, reducing test flakiness and preventing data leakage during test execution. Later, upgraded the codebase to require Python 3.10 or higher, removing Python 3.9 support and updating type hints and dependencies for future compatibility. The work demonstrated strong proficiency in Python, SQLAlchemy, and Pytest, focusing on maintainable, deterministic testing and modern backend development practices.
