Java Backend Developer building secure microservices with Spring Boot and cloud scalability.
IndiaWhat I'm looking for
I’m a Java Backend Developer with 3+ years of experience building scalable and secure enterprise applications using Java, Spring Boot, and Microservices Architecture. I focus on delivering robust REST APIs and event-driven systems, with secure authentication using OAuth2, Keycloak, and JWT.
In my recent role, I lead backend development of cloud-native microservices, integrating AWS services like S3, SQS, RDS, and Secrets Manager for high availability. Earlier, I developed 20+ REST APIs and optimized MySQL queries to reduce API response time by 35%, while integrating third-party services and improving reliability through debugging, performance tuning, and code optimization. I also work on AI/LLM integrations (GPT APIs, prompt engineering) to enable intelligent search, validation, and content processing, and I enjoy partnering cross-functionally to translate requirements into scalable technical solutions.
