I build full-stack learning platforms with React, Node.js, and MongoDB.

I built and deployed PlacePrep, a full-stack placement-preparation platform that brings DSA, company-specific interview problems, System Design visualizers, and Core CS subjects into one learning experience. I developed its search and filtering engine for 154 curated DSA problems, mapped 956 interview problems across 17 companies, and created 10 interactive SVG-based System Design visualizers.

I'm a Computer Science Engineering student with hands-on React, Node.js, Express, and MongoDB experience, plus a strong foundation in Data Structures & Algorithms, System Design, and backend development. I've solved 355+ LeetCode problems in C++ and completed a Citi technology job simulation involving real-time stock-market risk visualization, UML-based loan-management workflows, and credit-risk assessment recommendations.
