At PayPay Corporation, I’m building an in-house card processing platform and developing backend services for real-time payment authorization across five card networks.
I built event-driven microservices supporting workloads exceeding 1000 TPS per network, and drove the technical design for Hybrid Card integration. During an engineering assignment at PayPay’s Tokyo headquarters, I led production releases across the five network services and established production runbooks.
At Airtel Digital - Financial Services, I developed a unified customer identity platform and multi-offer loan eligibility capabilities that increased approval rates from 20% to 52.9%. At Airtel Digital - UPI Payments, I developed a transaction history microservice that reduced database load by 10%.
