About

Entry-level Full-Stack Developer with hands-on experience building end-to-end web applications using Java, Spring Boot, Spring Security, Hibernate/JPA, MySQL, REST APIs, JWT, and React.js. Built three full-stack applications covering backend API design, database modeling, authentication, authorization, and role-based access control, integrated with React.js frontends via Axios. Strong foundation in Core Java, OOP, Data Structures & Algorithms (182+ problems solved on LeetCode), SQL, and debugging across frontend, backend, and database layers. Comfortable independently breaking an idea down, building it, testing it, and iterating quickly, with a growing interest in using AI-assisted development tools (e.g. Claude, Copilot) to build faster while fully understanding the underlying code. Seeking an entry-level Full-Stack / Backend Developer role.
