PROFILE
Luzhania Cespedes Arancibia
Cesar Luzhania contributed to UCB-TallerDeDesarrollo/TDDLab by developing features that modernized both backend and frontend systems over three months. He implemented Firestore-backed APIs for branch and commit history, exposing endpoints that enabled granular test-run timelines and improved debugging. On the frontend, Cesar refactored UI components using React and TypeScript, simplifying user workflows and adopting a hexagonal architecture for modularity and testability. He also enhanced test infrastructure with Jest and robust mocking, ensuring reliable CI feedback. His work centralized data processing, reduced UI complexity, and improved maintainability, demonstrating depth in full stack development, API integration, and database management throughout the project.

Oct 1, 2025October 2025 (UCB-TallerDeDesarrollo/TDDLab): Delivered backend-first data processing modernization, frontend architectural refinement, and targeted UI cleanup, with a strong emphasis on correctness, test coverage, and scalable maintainability. Centralized data retrieval for commit history and cycles via new backend endpoints, enabling a leaner frontend and more consistent analytics. Refactored TDD Cycles Visualization into a hexagonal architecture with dedicated use cases, improving modularity and testability. Implemented comprehensive backend integration tests and QA tooling to validate data flows from GitHub to the application. This combination reduces UI complexity, enhances data reliability, and positions the project for faster iteration and future analytics.

Sep 1, 2025September 2025 monthly summary for UCB-TallerDeDesarrollo/TDDLab focusing on UI simplification and test infrastructure reliability. Key features delivered: UI/UX simplification by removing the unused Subir Sesión TDD button from TDDCommitTimelineDialog (commit 0951c679fd37098cd019e883c7d4e2709ad1f702). Major bugs fixed: implemented the missing obtainTDDLogs in all MockGithubAPI variants (MockGithubAPI, MockGithubAPIEmpty, MockGithubAPIError) to ensure consistent test behavior (commit 06862959a13f2a9a98b2bcd4183d4ca2c9f0a21b). Overall impact: streamlined UI reduces user confusion and maintenance cost, while the test suite becomes more reliable and deterministic across mocked environments, enabling faster iteration and safer deployments. Technologies/skills demonstrated: frontend UI/UX refactor, test infrastructure and mocking, clear commit hygiene and cross-repo collaboration.
