Lead Software Engineer at Mastercard who secured B2B notifications and redesigned core card modules.
IndiaWhat I'm looking for
At Mastercard, I secured B2B notification calls with JWT OAuth 2.0 and designed the Card and Cardholder module architecture, reducing defect escapes in those modules by about 35%.
I also drove a processor-agnostic migration that improved transaction throughput by 30%, and built a multi-channel notification system for more than 100,000 prepaid cardholders.
Earlier, at Zinnia (formerly SE2), I designed an integration framework and built REST APIs for the LifeCAD platform. Across fintech and insurance, I’ve worked on backend integrations, security, and automation, and I currently lead feature delivery at Mastercard.
