> Software Engineer | Java, Spring Boot, React & Node.js | Building High-Performance Distributed Systems | AWS Cloud

Location: New York, New York, United States
Profile: https://flows.cv/sandipkumar

I’m a software engineer with experience building scalable backend and full stack systems used in real production environments. I primarily work with Java and Spring Boot, along with JavaScript and TypeScript, and I’ve designed APIs, microservices, and data workflows deployed on cloud platforms like AWS.

Across startups and enterprise teams, I’ve worked on systems supporting 10K+ users, improved API latency by around 30–40%, and reduced production issues by introducing better state management, idempotency, and automated testing. I’ve owned features end to end, from schema design and backend logic to frontend integration and deployment, and I care deeply about reliability, maintainability, and developer productivity. I enjoy solving messy real world problems and turning them into systems teams can trust and scale.    

Currently based in New York City, open to remote or relocation across the U.S.
