MERN Stack Developer | React.js, Node.js, MongoDB | Passionate about building user-centric web applications | Open to new opportunities

About

Hi, I'm Rajneesh, a Full Stack Developer specializing in the MERN stack. I love taking an idea and turning it into a functional, responsive web application. During my internships at IonX Cyber Security and Celebal Technologies, I gained hands-on experience in optimizing React frontends for better performance and building secure backend APIs using Node.js and Express. I enjoy solving complex problems, whether it's debugging state management issues in Redux or structuring NoSQL databases. When I'm not coding, I'm usually exploring new tech trends or mentoring freshers in web development basics. I'm currently looking for opportunities where I can contribute and grow as an engineer.
