I’m a React.js-focused developer intern building end-to-end web applications, from responsive UIs to secure backend services. I’m currently pursuing an MCA while strengthening my fundamentals through Data Structures & Algorithms, OOP, and DBMS.

In my React.js Intern role, I expanded from frontend responsibilities into backend development, learning Python and FastAPI to support a Dealer Management System. I developed RESTful APIs with CRUD operations, JWT authentication, and Pydantic validation, and I designed PostgreSQL database schemas for dealer onboarding and inventory management.

As a Full Stack Web Development Intern, I built and deployed MERN applications with REST APIs, working through development, testing, debugging, and Git-based version control. I also bring strong collaboration habits using Agile practices and tools like Git, Jira, and Postman.

My projects reflect the kind of work I enjoy most: building reliable, user-friendly platforms. I developed a Fitness Tracking Platform with JWT-based auth and progress tracking, and a Zomato-inspired Food Ordering Platform with optimized MongoDB queries and scalable REST APIs—both deployed for real-world use.
