About Greg Serkin

At WNS (now part of Capgemini), I lead the Global Fintech Client Services Portfolio, with responsibility for executive client relationships, delivery excellence, and operational performance across a diverse set of high-growth and scaled fintech platforms. My focus is ensuring consistent, measurable outcomes as clients scale, transform, and operate in highly regulated environments. With over 20 years of experience across consumer lending, banking, and fintech operations, I bring a proven track record of translating strategy into execution, aligning people, process, technology, and governance to improve service quality, manage risk, and drive business results. I partner closely with C-suite and senior client leaders to modernize operating models, optimize service delivery, and ensure transformation initiatives deliver sustained value.Prior to joining WNS, I held senior leadership roles at global consulting firms and financial institutions, where I led large, cross-functional teams delivering complex programs spanning operations, risk management, compliance, and platform integration. My experience includes restructuring and liquidating non-performing loan portfolios, establishing enterprise risk frameworks and governance, streamlining end-to-end business processes, and supporting post-merger integrations across banks and non-bank lenders.I am known as a trusted client partner who combines executive presence with hands-on operational leadership. I excel at building and leading high-performing teams, strengthening governance and controls, and driving improvements in service quality, productivity, and account health. I am equally effective providing senior oversight for mature institutions or rolling up my sleeves in fast-growth fintech environments.Outside of work, I enjoy hiking with my family, running with my dog, and planning our next travel adventure. I also love hosting friends at home and cooking when time allows.Specialties: Fintech client services leadership, service delivery management, financial services operations, banking and consumer lending, mortgage banking, capital markets operations, managed services and BPO delivery, operating model transformation, governance and controls, enterprise risk management, compliance operations, non-performing loan resolution, post-merger integration, platform integration, account health and performance management, executive stakeholder management, service quality and KPI management, analytics and executive reporting, organizational design, talent development, change management.
