I am the Head of Data Science at NPCI, leading AI and data science innovation across India's digital payments ecosystem. With over 20 years of experience, I have built AI and machine learning solutions across fintech, retail, healthcare, edtech, HRTech, and analytics, helping organisations transform data into meaningful business outcomes.

My expertise includes Graph AI, Generative AI, temporal intelligence, machine learning, MLOps, federated learning, reinforcement learning, GPU-accelerated computing, and scalable AI platforms. I am passionate about translating cutting-edge research into practical, production-ready solutions that create real-world impact.

I am also an author, researcher, educator, and mentor. I am the author of Machine Learning for Finance and the creator of the Udemy course Data Analysis for Business and Finance, which has helped more than 22,000 learners worldwide build practical analytics skills. My research has been published and presented at leading international venues, including IEEE BigData, ICDE, GRADES-NDA/SIGMOD, IWANN, AIAI, and HiPC workshops.

Teaching is one of the most rewarding parts of my career. I believe the best way to learn AI and Data Science is by combining strong fundamentals with hands-on practice and real industry examples. Whether you are a student, working professional, or aspiring AI practitioner, my goal is to help you build confidence, develop practical skills, and apply AI to solve real-world problems.
