June 2025: Delivered a targeted fix to TiDB's TiFlash isolation read planner to correctly handle the primary index hint when PKIsHandle is true, preventing misidentification of the primary key as an index and improving query planning accuracy in edge-case isolation read scenarios. The change was committed to pingcap/tidb as a focused planner bug fix, enhancing robustness of the planner-TiFlash integration.

April 2025 — Delivered a SaaS-focused TiDB best practices guide to enable scalable, multi-tenant deployments. The documentation consolidates hardware configuration, region governance, caching, statistics collection, system table queries, connection management, stale reads, and backup/restore strategies to optimize performance and stability for environments with over a million tables. This work enhances onboarding, reduces deployment risk, and provides operators with a concrete reference for large-scale TiDB deployments.
