## About

```text
At Tata Consultancy Services, on the Johnson & Johnson engagement, I engineered role-based REST APIs with JWT authentication and RBAC across internal applications. I also designed a Spring Boot assessment platform with Flyway-managed schema migrations.

I designed and optimized PostgreSQL and MongoDB schemas, improving indexing and query performance and reducing average query response time by 20%. I also built React.js front ends integrated with REST APIs.

On my Remote Code Execution Engine project, I built a platform that runs code in sandboxed Docker containers and streams output in real time. I added a Redis-backed job queue and a Semaphore-based cap on concurrent container execution.
```
