Message

At FIONEER INDIA Pvt. Ltd., I lead development of backend microservices for a bank’s core payment platform using Java, Spring Boot, and REST APIs. My work on REST APIs improved transaction processing speed by 30%, and I integrated OIDC and SSO across banking applications.

I also led migration of legacy monolithic systems to microservices and designed containerized services deployed on Kubernetes. Earlier at SAP India Pvt. Ltd, I developed microservices for customer onboarding and loan processing, with OIDC-based SSO and monitoring using Prometheus and Grafana.
