Linnea Renman contributed to the HGustavs/LenaSYS repository by building and refining backend microservices focused on course provisioning, API reliability, and maintainability. She consolidated and clarified the microservice inverse dependency map, re-engineered retrieval logic for codeviewer and highscores services, and introduced a GitHub-based endpoint for automated course material import. Her technical approach emphasized PHP and SQL for backend logic, with thorough documentation and expanded unit testing using PHPUnit. By centralizing inter-service communication and improving documentation, Linnea reduced onboarding friction and deployment risk, demonstrating depth in API development, database management, and microservice architecture over the course of two months.

May 2025 performance summary for HGustavs/LenaSYS: Delivered major improvements to course provisioning from GitHub, strengthened testing and documentation, and refactored inter-service communication to improve security and maintainability. The month focused on delivering business value by enabling automated course material retrieval, improving onboarding through better docs, expanding test coverage for critical services, and centralizing cross-service calls via a curl-based approach.

April 2025 – LenaSYS: Delivered two primary improvements focused on maintainability and API reliability. Key features delivered include Documentation: Microservice inverse dependency map consolidated across microservices with folder-name context and no-dependency notes; Codebase Refactor: Microservices codeviewer and highscores with enhanced retrieval logic, API usage improvements, and POST standard alignment. Major bugs fixed: typo corrections in documentation and filename (copyCourseVersion_ms.php) and clarifications to inverse dependency notes to prevent misconfigurations. Overall impact: clearer dependency topology, reduced onboarding friction, safer deployments, and more robust microservice APIs, enabling easier future changes. Technologies/skills demonstrated: microservice architecture understanding, API design and standardization, PHP-based service mapping and refactoring, and thorough documentation practices.
