About
Building products that solve real problems—not just projects that sit on GitHub. I'm a MERN Stack Developer and Computer Science undergraduate passionate about creating scalable web applications, real-time systems, and AI-powered products. My expertise spans React.js, Next.js, Node.js, Express.js, MongoDB, and cloud deployment. I enjoy turning ideas into production-ready solutions while focusing on clean architecture, performance, and user experience. During my Full Stack Development internship, I engineered and deployed multiple web applications, improving page load performance by 30% through optimization techniques. I also built a real-time code collaboration platform using WebSockets to support concurrent users. Previously, as an AI Intern, I integrated machine learning models into production applications serving 500+ users and developed data pipelines that improved processing efficiency by 25%. Beyond internships, I've built projects such as ResumeIQ, an AI-powered resume analyzer, and a full-stack URL Shortener with analytics, authentication, and Dockerized deployment. Currently, I'm seeking Software Engineer, Full Stack Developer, and MERN Stack opportunities where I can contribute to impactful products, grow alongside talented teams, and deepen my expertise in scalable systems, cloud technologies, and AI-driven applications. I'm especially excited about building solutions at the intersection of Full Stack Development, Generative AI, and modern web technologies. Let's connect and build something meaningful.
