I’m also comfortable developing end-to-end applications using React.js and modern UI tools. Tech Stack: Java, Spring Boot, Spring Security, REST APIs, GraphQL, Docker, AWS (DynamoDB), MySQL, PostgreSQL, MongoDB, React.js, Tailwind CSS, Shopify, Git, Postman I’m particularly interested in backend architecture, API design, and performance optimization, with a focus on writing clean, scalable, and maintainable code.
