Month 2025-11 highlights: Focused on improving test reliability and release readiness through CI/CD workflow modernization for PMM UI tests. Delivered end-to-end testing changes: switched end-to-end tests to run on the main branch instead of v3, and removed the scheduled cron trigger for PMM E2E tests to enable manual triggering, ensuring tests always run against the latest code. No major bugs fixed in this period for percona/pmm-ui-tests; efforts concentrated on reliability and speed of feedback. Impact includes reduced code-test drift, faster release cycles, and improved confidence in deployment readiness.

Monthly summary for 2025-10: Focused on optimizing PMM Server deployment by disabling Query Analytics (QAN) monitoring to reduce overhead and simplify deployment. Key change implemented in percona/pmm-ui-tests: removed the QAN enablement environment variable in Docker Compose (commit fdc31afa555d7943b9d9c546f5c7e73abcaf4610, PMM-11406). This reduces resource usage, lowers operational cost, and streamlines rollout of PMM Server instances. No major bugs fixed this period. Overall impact: lighter PMM Server footprint, faster deployments, and easier maintainability across environments. Technologies/skills demonstrated: Docker Compose configuration, environment-variable-driven feature toggling, change management with traceable commits, and end-to-end deployment discipline.
