What I'm looking for

I’m looking for a role where I can build scalable MERN/Java web apps, own real-time features and REST integrations, and grow in AI automation/agentic workflows with supportive mentorship.

I’m a Full Stack Developer with hands-on experience in MERN Stack, Java, and REST API integration through internships and academic projects. I build responsive web applications, authentication systems, and real-time features using React.js, Node.js, MongoDB, and Socket.IO, with a strong focus on turning technical ideas into user-focused outcomes.

In my recent internship, I built a real-time chat app with bidirectional communication and integrated the OpenWeather REST API to deliver live weather across 100+ cities with sub-second responsiveness. I also designed core Java console applications applying OOP principles and shipped with zero critical bug reports.
