Jun Yao developed and enhanced backend features for the Camyo-ISPP/CamyoApp and Documentacion repositories, focusing on scalable REST APIs, robust data layers, and automated testing. Over four months, Jun implemented authentication-bound CRUD operations, subscription management with tiered plans, and comprehensive unit and load testing using Java, Spring Boot, and Python. The work included designing service and repository patterns, integrating CI/CD pipelines with GitHub Actions, and improving documentation for onboarding and transparency. Jun’s contributions emphasized maintainable code, clear API boundaries, and performance visibility, resulting in improved test reliability, streamlined load testing, and better alignment between engineering quality and business needs.

May 2025 performance-focused delivery across two repositories. Key enhancements: (1) Documentacion: New Performance Evaluation - Student Contributions section added with a formal sticker template to document student involvement, plus comprehensive contributor details (documentation tasks, code review, meeting participation, final meeting). (2) CamyoApp: Lokust load testing script cleaned for the Camionero feature by removing redundant imports and unused class definitions to improve clarity and maintainability of the load tests.

Month: 2025-04. Concise monthly summary focusing on business value and technical achievements for CamyoApp and Documentacion: Key features delivered and improvements: - Comprehensive unit testing for core modules (Reseña, Suscripción, Usuario): added new tests, performed refactors, and removed redundant tests to improve reliability and coverage across the critical backend paths. - Backend load testing with Locust across modules: introduced an end-to-end load testing framework for the CamyoApp backend (subscripciones, reseña, payments, camionero, and more) with clear documentation to guide setup and execution, enabling early bottleneck identification and scalability assessment. - Documentation enhancement in performance evaluation: documented student contributions (test implementation, bug fixes, PR reviews, and documentation reviews) for transparent sprint reporting in Documentacion. Major bugs fixed and stability improvements: - Several test-suite fixes addressing flaky tests and coverage gaps, including targeted fixes for usuario-related tests and overall testing structure to improve stability and confidence in deployments. Overall impact and accomplishments: - Improved test reliability, coverage, and maintainability; enhanced performance visibility and scalability readiness; increased transparency into team contributions; and stronger alignment between quality engineering and business value. Technologies/skills demonstrated: - Unit testing, test automation, test-driven improvements, Python-based testing workflows, Locust-based load testing, performance benchmarking, and documentation best practices.
