About
Hi, I’m Amartya Rana. I’m a Sr Java Full Stack Developer with 8 years of experience delivering cross-platform web and client-server applications. I specialize in Java 8/11/17, Spring Boot, Microservices, and REST API development, with a strong grounding in core Java concepts such as Lambdas, Streams, and functional interfaces. I’m proficient with Agile (SCRUM) and Test-Driven Development (TDD), building scalable solutions, writing clean code, and iterating quickly in fast-paced environments.
I enjoy collaborating with UI/UX teams to design intuitive front-ends and reusable backend components. I’ve worked with ReactJS and Redux for state management, deployed services on AWS/PCF with Docker, and consistently contribute to CI/CD and performance tuning efforts. I’m motivated to help teams adopt best practices in testing, security, and reliability while mentoring colleagues to grow technical excellence.
