About

Senior Data Analyst working at the intersection of customer analytics, retail performance and data-driven growth. My work focuses on transforming complex datasets into insights that help organizations understand customer behaviour, measure performance and make informed strategic decisions. With experience across e-commerce, telecom and technology companies, I have worked on analytics initiatives spanning CRM performance, campaign measurement, customer segmentation and growth analytics. This includes analyzing large-scale datasets, developing analytics frameworks and building dashboards that enable teams to track performance and identify opportunities for improvement. My technical toolkit includes SQL, Databricks, Tableau and AWS, along with modern analytics platforms such as GA4 and Mixpanel. I enjoy working in cross-functional environments where analytics, business strategy and product thinking intersect, helping teams translate data into meaningful insights that support long-term growth and better decision making.
