Investigation Associate @ Amazon

About me

I'm Navina, a data enthusiast with a knack of transforming raw data into meaningful, actionable insights.

At Amazon, I mastered the art of analyzing and resolved over 25,000 Photon OTC UoWs across low, medium, and high complexity levels, honing my expertise in Unit of Works (UoW). I’ve since advanced to managing over 1,500+ complex end-to-end cases monthly in the Guided Work Flow (GWF) system, ensuring seamless case handling and delivering impactful outcomes.

Leveraging tools like Power BI, SQL, and Python, I create visually compelling dashboards, extract insights from complex datasets, and design efficient workflows that drive smarter business decisions. Whether it's identifying trends or optimizing processes, I'm all about using data to make an impact.
