I’m a B.Tech Computer Science & Engineering student (NIT Kurukshetra) and a Software Developer Intern who enjoys building systems that are both fast and reliable. I like working close to the backend—optimizing performance, strengthening resilience, and shipping improvements that hold up in real conditions.

In my internship at TestnSolve, I designed and optimized backend APIs using Node.js, reducing average response latency by 30% through query optimization and efficient data handling. I also enhanced system resilience by refactoring legacy modules, implementing structured error handling, debugging production edge cases, and improving backend reliability.

My projects blend engineering with practical AI: I built a Real Estate Price Prediction & Recommendation System using Selenium-based scraping and ML (Random Forest) plus a weighted recommendation engine. I also developed an AI-Powered Resume Analyzer using NLP (TF-IDF + cosine similarity) with a Streamlit interface, and a secure School Management System with JWT-based authentication and role-based access control (RBAC).
