Aspiring MERN stack developer building secure REST APIs and AI chatbot web apps.
IndiaWhat I'm looking for
I’m an aspiring MERN Stack Developer and B.Tech IT student focused on building RESTful APIs, secure backend systems, and AI-integrated web applications. I enjoy turning well-defined requirements into reliable, testable features that users can trust.
In my projects, I built a UPI-style backend REST API with Node.js, Express.js, and MongoDB, including atomic debit/credit transactions using idempotency keys to prevent duplicate payments. I also implemented secure authentication using JWT and bcrypt, plus automated email notifications with Nodemailer.
I’ve also developed a full-stack AI chatbot application with a React frontend and a Node.js/Express backend, integrating the Google Gemini API for intelligent, context-aware responses. My approach is hands-on, security-minded, and grounded in strong fundamentals like DSA, DBMS, and OOP.
