Month: 2025-11 | Repository: marcosdosea/gcm-ufs. Summary: Delivered foundational client data management and sales workflow with a focus on value and stability. Key items include the Client Management Module (GerenciadorCliente) with insert and consult (foundation for remove/modify), later extended to remove/modify client data; and the Sales Management Module (GerenciadorVenda) to finalize and cancel sales. A rollback was performed on the Client Management feature due to instability to preserve a stable baseline. Impact: established end-to-end client data and sales lifecycle support, improved data governance, and a stable release path. Technologies/skills: modular design, disciplined Git-based traceability, issue-driven development (linked to #1973-#1975), and rollback strategy for quality control.
