About

I build supply chains that make GW-scale renewable energy cheaper to deliver. Currently leading raw material procurement for a 6.6 GW solar module plant and a 2.9 GW solar cell plant at EMMVEE Photovoltaic — one of India's largest integrated solar manufacturing operations. Over 16 years, I've built procurement functions, not just run them. At Tata Power Solar, I led a team of 8 buyers managing $100M+ in direct and indirect spend across India and APAC — cutting procurement cycle time by 50%, saving $10M annually through automation, and delivering 15–20% average annual savings through structured supplier negotiations.
