Over a two-month period, contributed to the marcosdosea/gcm-ufs repository by developing foundational backend features for client and sales management workflows. Built modular Java components using object-oriented programming, including a Client Management System with CRUD operations and a Sales Management System supporting full sales lifecycle management with state safeguards. Addressed maintainability through architectural refactoring and regression fixes, demonstrating attention to code quality and traceability. Integrated file management artifacts to support classroom training and documentation. The work established scalable structures for future enhancements, improved data integrity, and ensured reliable user feedback, reflecting a methodical approach to backend and full stack development.
November 2025 — marcosdosea/gcm-ufs: Key features delivered, major bugs fixed, and notable impact. Features delivered: Client Management System (GerenciadorCliente) introduced CRUD capabilities for client records via a dedicated GerenciadorCliente class, with methods to insert, consult, update, and remove clients (commits: 8625672f7af177178e6d39e7f391f9f4d0f39ec8; e314c884abe5c2d3c1b799261c19cf93d4d064c3; 7519bf396ba8236d84c7c165df80b6f65133534e; 951c05994c420328953115ec71a201ee0bd46885). Sales Management System (GerenciadorVenda) added end-to-end sales lifecycle management with Finalize and Cancel operations, including safeguards against invalid state transitions and clear user feedback (commits: eb674d0c83cc809ba71770ba5aa545d6b4591fee; 7370e5c3f6fb95faa77715a2a86c76be3817dc36). Major regression fix: removal of GerenciadorCliente and GerenciadorVenda classes as part of a refactor, indicating architecture simplification or restructuring (commit: 496b782c947b05cb3b4c1d943d40ed86226d106d). Impact: Enables reliable client and sales workflows, improves data integrity, reduces operational risk, and lays groundwork for future enhancements; Technologies/skills demonstrated: object-oriented design, modularization, CRUD patterns, state management, documentation and traceability via commit messages and issue refs (#1956, #1957, #2025, #2027, #2028, #2029).
