As a MERN Stack Developer, I specialize in building modern, efficient, and scalable full-stack web applications using the MERN stack:
MongoDB – NoSQL database for high-performance and flexible data storage.
Express.js – Fast, minimalist backend web framework for Node.js.
React.js – Modern frontend library for building rich user interfaces.
Node.js – Asynchronous event-driven JavaScript runtime for building scalable server-side applications.
