At Zupee, I architected modular payment infrastructure for an app with 100M+ downloads, integrating Razorpay, Juspay, PhonePe, Paytm, Amazon Pay, and Google Play Billing. My delegate-based failover framework improved transaction success by 12%, while real-time checkout socket modules increased user engagement by 5%.
I’ve also co-developed design systems, server-driven UI, and standardized MVVM/MVI architectures that cut feature engineering cycles by 50%. Previously at Amity Software Systems, I launched 15+ native applications for government, insurance, and enterprise clients, including the UP Government E-Ganna platform with more than 3 million downloads.
