about me

Engineering at scale,
shipping with purpose.

I'm a Software Engineer based in Pune, India with 5+ years of experience building high-scale backend systems and distributed infrastructure. My career spans from building ERP automation at Aptean, to owning mission-critical systems at Amazon, to leading AI-powered platforms at PhonePe.

At PhonePe, I architected a multi-tenant AI analytics pipeline serving 4 business lines — consumer payments, merchants, insurance, and share.market — delivering automated agent performance evaluation and saving ~₹2 Crore annually.

At Amazon, I owned the AMXL post-purchase notifications platform handling hundreds of thousands of orders daily and drove an 8.3 bps reduction in customer contact rate.

When I'm not architecting systems, I'm managing my SIPs, tracking the stock market 📈, or planning my next international getaway ✈️
