I implemented a secure authentication flow with a standard identity provider, enabling seamless and centralized login. I handled token validation, session management, and secure user identity processing. This reduced login friction while maintaining strong security standards, and I delivered a stable, production-ready authentication system within a tight deadline.

I used AWS services like Lambda, API Gateway, RDS, and S3 to create a system that scales without manual infrastructure management. I designed pipelines for ingesting and processing live data to support trading signals and sentiment analysis. My focus was on keeping latency low, handling high concurrency, and ensuring the platform remained stable for global users.
