About

Full-stack developer focused on building and shipping products fast using React, Node.js, FastAPI, Flask, and MongoDB. Built ContestHopper (contesthopper.live) to solve the messy problem of discovering coding contests, using MongoDB Atlas Search for fast, fuzzy matching. Also built Ksheeram, a multi-seller e-commerce platform (Flask + React), and DataSage AI, a FastAPI tool for querying datasets with LLMs. I enjoy working across the stack, taking ideas from concept to production, and iterating based on real usage. Graduating April 2026 (B.Tech, AI & ML). Open to fully remote roles worldwide.
