About

I work at the intersection of growth, portfolio strategy, customer lifecycle, and analytics in financial services. Over the past 12+ years, I’ve built my career across consulting, fintech, startup environments, and global institutions, leading mandates focused on growth, profitability, customer engagement, and transformation. That mix has shaped how I solve problems — with structured thinking, a strong commercial lens, and a bias for scalable outcomes. At American Express India, I lead the customer engagement and business insights charter for the Consumer Cards business. My work spans lifecycle strategy, communications, retention, portfolio interventions, and analytics-led decisioning across customer journeys that influence activation, engagement, spend, attrition, compliance, and customer experience. I also work closely with cross-functional teams across product, risk, compliance, technology, and servicing on business-critical initiatives and transformation priorities. Prior to this, I worked in fintech, where I helped build growth capabilities across acquisition, CRM, partnerships, content, and funding journeys in a relatively 0-to-1 environment. Earlier in my career, consulting laid the foundation for structured problem-solving, stakeholder management, and disciplined execution. I’m especially interested in conversations around portfolio growth, lifecycle strategy, retention, customer decisioning, premium financial products, and analytics-led leadership. Always happy to connect with people working across cards, lending, wealth, payments, fintech, and consumer growth.
