April 2025: Implemented Monthly Data Diff Monitoring Cadence in datafold/demo by changing the cron schedule from weekly on Mondays at noon to monthly on the first day of each month at noon across all data diff monitors and related database integrations. This provides predictable monitoring cycles, reduces weekly compute overhead, and improves alignment with monthly business reviews. Commit 4bd41f1443da3a74d07299ab461b594e255ec102 documents the change. No major bugs fixed this month. Overall impact: increased reliability and efficiency, with clear traceability via Git history. Technologies/skills demonstrated: cron scheduling, cross-database monitoring orchestration, Git-based traceability, and multi-repo coordination.
