I'm aFull Stack Java Developer

Sai Reddy

Full-Stack Developer | Scaling Distributed Systems

Started as a Software Developer building enterprise backend systems. Led the transition from monolithic architecture to event-driven microservices, handling 100K+ concurrent users. Now at Nutrisystem as Sr. Backend Engineer, building payment systems and meal planning APIs.

My sweet spot: taking complex distributed systems and making them faster, more resilient, and easier to operate. Microservices, event-driven architecture, and cloud-native design are my core strengths. But I don't stop at backend—I deliver full-stack solutions with React/Next.js frontend expertise.

I believe in clean architecture, measurable performance, and observable systems. Code isn't done until it's monitored, tested, and documented. Great engineers lift up their teams.

Pursuing AWS Solutions Architect certification. Always learning—currently exploring Go for microservices and Spring AI.
