Professional Summary

I am a Java Developer with over 4+ years of experience in developing and maintaining enterprise applications, microservices, and cloud-based solutions. I have strong expertise in Java (8/11), Spring Boot, Spring Cloud, and Hibernate, with experience in building secure RESTful APIs and integrating systems. I have worked with AWS (ECS, Lambda, EC2, S3, RDS) to deploy and manage scalable applications, ensuring high availability and security. I have contributed to projects at Apisero, Chandler, Arizona, where I developed microservices and automated CI/CD pipelines, IGCB, Chennai, Tamil Nadu, where I optimized banking applications and migrated systems to microservices, and Algocode, Pune, Maharashtra, where I designed enterprise solutions and containerized applications. My skills include working with Docker and Kubernetes for containerization, using Jenkins and AWS CodePipeline for CI/CD automation, and ensuring secure access control with Spring Security, OAuth 2.0, and JWT. I am also experienced in optimizing databases with PostgreSQL, Oracle, and MongoDB, and improving application performance using Redis and ElastiCache. I work well in agile environments, collaborating with teams to align development efforts with business goals. I also mentor junior developers and document key processes to ensure knowledge sharing and team growth.
