I've built production-grade enterprise systems for ServiceNow, NPCI's BHIM UPI platform, and BYJU'S across SaaS, FinTech, and EdTech.

At ServiceNow, I redesigned loading architecture for large enterprise datasets, reducing page load time from 60+ seconds to under 10 seconds. I also built a GenAI-integrated Resource Finder and resolved 80+ P1/P2 production escalations.

Previously at NPCI, I developed distributed Java services for BHIM UPI using Kafka and Redis, reducing missed payments by 20%. At BYJU'S, I built backend APIs, resolved 100+ production defects, and automated reporting dashboards that saved about 50 hours each month.
