Have you worked on Amazon QuickSight?

Yes, I have worked extensively with Amazon QuickSight in my recent role at XYZ Corp. I was responsible for designing and deploying interactive dashboards for the sales and marketing teams. I started by gathering requirements from stakeholders, then mapped the data sources—primarily an Amazon Redshift data warehouse and an S3 data lake—into QuickSight datasets. Using QuickSight’s SPICE engine, I optimized query performance by creating appropriate data models and applying filters to reduce data volume. I also leveraged QuickSight’s ML Insights to surface anomaly detection and forecast trends, which helped the business identify underperforming regions and adjust campaigns accordingly.

In addition to dashboard creation, I automated the refresh schedule using AWS Lambda and CloudWatch Events, ensuring that the visualizations were always up-to-date without manual intervention. I also integrated QuickSight with AWS Cognito for secure, role‑based access control, allowing users to view only the data relevant to their department.

Overall, my experience with QuickSight has given me a solid understanding of data modeling, performance tuning, and user‑centric design in a cloud BI environment.
