About Sayak Bhattacharya

I help global enterprises design and execute $100M+ cloud, AI, and platform transformation programs across banking, insurance, and regulated industries.I lead enterprise transformation initiatives at the intersection of large-deal strategy, cloud and AI modernization, and global delivery execution.Over the past 20+ years across Cognizant, Infosys, TCS, and Tech Mahindra, I have helped global organisations translate complex transformation agendas — cloud, AI, ERP, and managed services — into commercially viable, scalable operating models.My experience spans India, the US, UK, Australia, EU, Canada, and Latin America, working with some of the world\'s most demanding institutions including ABN AMRO, AXA, Westpac, VISA, Asian Development Bank, iPSL UK, Franklin Templeton, AVEVA (Schneider Electric), LabCorp, Johnson & Johnson, KPMG, and British Petroleum.A defining chapter of my career was at TCS, where I built and launched a nearshore delivery centre in Mexico from the ground up for LabCorp (S&P 500). Defined the operating model, hired and trained the engineering teams, and scaled the engagement to deliver 400% year-on-year bottom-line growth.That experience shaped how I think about enterprise transformation: scaling delivery is not just a logistics challenge — it is fundamentally about governance, trust, and sustainable operating models.My core focus areas include:• Enterprise cloud and platform modernization• AI and GenAI-enabled transformation programs• Large deal architecture and commercial structuring• Global delivery operating model design• Managed services transformation at enterprise scaleI specialize in designing transformation programs that balance capability vs capacity, cost vs risk, and speed vs control, ensuring that architecture can be sold, delivered, and sustained at scale.I am most effective in environments where technology decisions directly influence enterprise revenue, operating efficiency, and long-term client trust.Alongside my corporate work, I serve as Senior Mentor at NASSCOM Foundation, training and supporting the next generation of leaders in technology.Education: IIM Nagpur — Senior Management Programme.Open to leadership roles in: • Director / AVP / VP Technology Transformation
