Message

At CIGNA / EVERNORTH HEALTH SERVICES, I established reliability governance across a healthcare portfolio and introduced a shift-left reliability model across 200 critical microservices. I also developed reusable AI-driven analysis for over 100 services, reducing assessment efforts from a week to hours.

I directed the cloud-modernized launch of a critical claims-routing platform with zero related support incidents, recognized with the 2021 Dragon Award. Earlier, at SUPERVALU (TCS), I directed the migration of over 50 enterprise applications from proprietary middleware to open-source platforms.
