Oct 1, 2025Performance-focused month for OoS-Backend (2025-10). Focused on data integrity, draft persistence, and moderation efficiency. Key features delivered include: (1) Consolidation and validation of CompetitiveEvent DTOs to strengthen data integrity across creation flows; (2) Temporary Save/draft workflow for CompetitiveEvent with new DTOs, dedicated controller, and tests, increasing robustness of draft handling; (3) Moderation efficiency improvements by skipping moderation when fields are null or empty, reducing review overhead; and (4) Stability fix for the CompetitiveEvent Update workflow to improve reliability. Overall impact: stronger data quality, more reliable draft management, and faster moderation cycles, resulting in clearer review paths and reduced rework for CompetitiveEvent-related submissions. Technologies/skills demonstrated: DTO validation patterns, controller and workflow design for draft saving, test-driven push for new flows, and moderation logic refactoring.
