About Chintan G

I’m a Java Backend Developer with over 3 years of experience building scalable, cloud-native applications and delivering high-impact features for enterprise systems. My expertise lies in Java, Spring Boot, Microservices, REST API development, and database optimization — combined with strong skills in performance tuning, security implementation, and CI/CD automation.At IBM, I’ve designed and developed high-performance APIs, implemented JWT-based authentication with Spring Security, optimized MySQL schemas and queries for faster data access, and integrated Redis caching to improve scalability under heavy traffic. I’ve also automated CI/CD pipelines with Jenkins, containerized deployments with Docker and Kubernetes, and improved code quality through SonarQube and robust test coverage using JUnit & Mockito.I thrive in Agile/Scrum environments, collaborating with cross-functional teams to deliver features on time and resolve production issues quickly. My approach is always results-driven, ensuring secure, reliable, and maintainable code that supports business growth.Key Skills: Java, Spring Boot, Hibernate, Microservices, REST APIs, PostgreeSQL, Kafka, Redis, AWS, Docker, Kubernetes, Jenkins, Git, SonarQube, Agile/Scrum, Performance Optimization, API Security.
