## About

```text
At Amazon, I led the design of a distributed token-caching layer for Amazon S3 and AWS Access Points to prevent downstream services from failing to start during authentication outages.

I also spearheaded the migration from legacy symmetric-key authentication to OAuth 2.0. Automated AWS Step Functions workflows supported the phased migration, which achieved zero downtime as legacy traffic fell by 87%.

For Amazon’s authentication platform, I led implementation of a Java client-side caching module across AWS Lambda, ECS, and EC2. I also redesigned TLS certificate distribution, reducing service-to-service authentication latency by 37%, and extended AuthN/AuthZ to support AI Agents and MCP Servers.

At CDOT, I engineered real-time blocklisting and access-control modules for an internal video-calling platform, and resolved client-side issues in its iOS application using Swift. Earlier, as an Amazon intern, I developed integration tests and a Kotlin AWS Lambda function. In my Paytm Saarthi project, I built an AI procurement and inventory copilot using React, TypeScript, Sarvam AI, Supabase, and PostgreSQL.
