What I'm looking for

I want to contribute as a Software Engineer to build scalable full-stack products—clean APIs, responsive React UI, and real-time features—while working in a collaborative environment that rewards ownership, problem-solving, and continuous learning.

I’m a final-year B.Tech CSE student with strong Java and DSA fundamentals, and I build full-stack web applications with a focus on reliability, performance, and good developer experience. I’ve worked with Node.js/Express, MongoDB, RESTful APIs, and real-time features using WebSockets (Socket.IO), while keeping UX in mind with React.js and Tailwind CSS.

In my projects, I built Prepwise, an AI-powered mock interview platform with real-time voice interviews, live transcripts, role-based dynamic question generation using Groq LLM, and an analytics dashboard with trends, heatmaps, and PDF reports. I also engineered ChatPulse, a low-latency real-time chat application with presence tracking, optimistic UI updates, session synchronization across devices, and MongoDB indexing for fast chat history retrieval—securely integrating JWT authentication. I’m a quick learner who enjoys debugging, problem-solving, and shipping useful features in dynamic, collaborative environments.
