## About

```text
At National Informatics Centre, I designed and built UDISE+ Auth, a centralized OAuth2 and OpenID Connect authorization server serving 1.4M+ users across 7 applications. I implemented SSO and SLO, along with Redis-backed distributed session management and OTP-based two-factor authentication.

I also developed secure backend modules and REST APIs for UDISE+ account management, user management, and its API portal. Previously, at Addup Networks Pvt Ltd., I implemented Java and Spring Boot APIs for transport and warehouse management systems.
