Debashish Chakraborty

I’m a results-driven Lead Data Analyst with 15+ years of experience across global banking and technology organizations, including Wells Fargo, IBM, and American Express. I translate business vision into clear user stories, acceptance criteria, and data-backed insights that improve lending, customer journey, payments, and liquidity outcomes.

At Wells Fargo, I’ve supported Product Managers with backlog prioritization and sprint planning, mapped user journeys, and documented functional & nonfunctional specifications while acting as a liaison between Product, Engineering, Design, Compliance, and Finance. I build and deliver optimized SQL pipelines, real-time BI dashboards in Power BI and Tableau, and automated workflows using Copilot and Power Automate—driving a 10% improvement in VOC satisfaction and a 15% uplift in engagement. I also led Power BI cloud migration, A/B testing setup, and automated JIRA workflows, plus I’m currently creating an AI product using Model Context Protocol (MCP).

Previously at IBM, I built Tableau/Cognos dashboards improving marketing enablement by 35% and analyzed VOC insights to guide product strategy. I automated SQL financial reporting, reducing delivery time by 37%, and at British Telecom I delivered analytics that saved 120+ man-hours through statistical validation—consistently helping teams make faster, better decisions with measurable impact.
