I've built KPI dashboards, operational reports, and data-validation workflows that turn business requirements into reliable insights using SQL, Python, Power BI, and Excel.

In a Blue Bikes database project, I redesigned and indexed a 100K+ row PostgreSQL database, reducing query latency by 30%. I also maintained 10+ recurring usage reports with scheduled refreshes and validation.

I analyzed 500+ British Airways customer responses to identify a 33% satisfaction drop and a 56% experience gap across flight classes and routes. My Python visualizations made monthly sentiment trends faster to interpret.

Across sales, workforce, and Formula 1 telemetry projects, I've used dashboards, variance analysis, forecasting, and root-cause investigation to help stakeholders isolate performance gaps and make data-backed decisions.
