Marouane Bellari developed the backend for JoelvanIngen/Competitive-Green-Coding, focusing on a robust API core to support secure user management, frontend integration, and energy telemetry. He established a FastAPI scaffold with SQLAlchemy for database operations and implemented asynchronous HTTP handling using httpx. The work included designing Pydantic v2 schemas for data validation, introducing token-based authentication, and adding privacy controls to support user opt-out and data compliance. Marouane enhanced the testing framework with Pytest fixtures and server-side tests, improved code quality through refactoring and linting, and optimized database queries, resulting in a maintainable, scalable foundation for future feature delivery.
June 2025 performance summary for JoelvanIngen/Competitive-Green-Coding. Focused on delivering a robust API core, enabling frontend integration, tightening testing and infrastructure, and advancing data-driven features with privacy controls. Business value centers on secure, scalable backend services, greener computing telemetry, and clearer, testable data flows for faster iteration and higher quality releases. Key accomplishments: - API core/auth improvements (Issue #5): Established FastAPI app scaffold, SQLAlchemy get_session dependency, and authentication flow (UserRegister/UserLogin/TokenResponse); migrated to async HTTP with httpx; updated validation and password handling with Pydantic v2 schemas. These changes lay the groundwork for secure, scalable user management and easier client integration. - Frontend integration endpoints scaffolding (#36): Added frontend-facing API surface and integration hooks to streamline UI work and reduce future rework. - Testing framework and infrastructure upgrades: Introduced conftest fixtures, initial server-side tests and power-usage checks via scaphandre; improved test coverage and reliability. - Data model and query enhancements: Implemented energy-based query ordering, added energy/emissions fields to submissions and related schemas, introduced UUID-based lookups, and propagated avatar_id through tests and user models to improve reporting fidelity. - Privacy and opt-out controls: Added opt-out/private functionality in queries and tests, with explicit handling for private/not-found users and leaderboard privacy checks. This supports compliance and user trust while preserving data utility. Overall impact: - A more secure, maintainable, and observable backend foundation enabling faster feature delivery, better data insight (energy and emissions telemetry), and improved privacy controls. The changes reduce integration risk for frontend teams and provide a clearer path for performance and reliability improvements in the next cycle. Technologies/skills demonstrated: - FastAPI, SQLAlchemy, httpx (async), Pydantic v2, UUID handling, token-based authentication, and secure data transfer patterns. - Testing strategies with conftest fixtures, server-side tests, and power-usage integration. - Code quality and tooling: lint/isort, formatting, endpoint cleanup, and robust error handling.
