About

I build engineering organisations and platforms that scale — from the first hire to hundreds of people, from zero to systems that move millions of transactions a day. 16 years across Amazon, Walmart, Piramal Finance, and AI-native startups. I've led large-scale e-commerce and last-mile delivery infrastructure at Walmart, built Piramal's in-house engineering org from 0 to 200+ people supporting a ₹70,000 Cr retail lending business, and most recently architected AI pipelines — RAG, voice AI, agentic systems — in production at scale. — 📌 200+ engineers built from scratch at Piramal, reporting directly to the CTO 📌 Built and led the team for Walmart's last-mile system for online grocery delivery 📌 Coded the sourcing platform for Walmart.com from scratch — What I care about most: hard engineering problems at the intersection of AI and product, and the organisational work that makes exceptional engineering possible — hiring, culture, structure, and the conditions where great teams do their best work. I'm a BITS Pilani alumnus and a winner of Piramal's ASCEND Leadership Programme, evaluated by Ajay Piramal and Nandini Piramal.
