Can you talk about any projects you have worked on, the issues you faced, and how you resolved them?

Sure. In my last role at XYZ, I led a migration project from on-premise to a cloud-based data warehouse. The biggest issue was maintaining data consistency during the cutover. I implemented a two‑phase commit strategy combined with incremental data sync and automated rollback scripts. I also set up a monitoring dashboard to detect anomalies in real time. As a result, we achieved 99.9% data consistency, reduced migration downtime by 40%, and improved query performance by 25%. This experience taught me the importance of thorough testing, clear rollback plans, and proactive monitoring.
