I’m a Full Stack Developer with 1 year of production experience building MERN stack applications at scale. I’ve shipped AI-powered platforms and data systems processing 3M+ records, with a strong focus on performance, reliability, and scalable architecture.

At OMR India Outsources Pvt Ltd, I designed and scaled a web-based OMR data entry platform with CSV and image ingestion. By automating MySQL table creation and task allocation, I increased capacity from 50K to 3M+ records while supporting 5000+ concurrent users.

I also improved image-based OMR scanning accuracy to ~98% by optimizing template-driven frontend workflows, reducing lag for high-volume processing. In parallel, I built full-stack AI-driven business guidance APIs using React, Node.js, and FastAPI for AI recommendations, coach hiring, and user management.

On the product side, I built an Onscreen Marking Software with React, Node.js, MongoDB, Redis, and Bull Queue—supporting bulk PDF booklet processing, real-time annotation via Socket.IO, and multi-role RBAC (JWT + OTP) with automated CSV result generation. Earlier, as a Software Engineer (React) Intern, I led MERN development efforts, contributed to 2+ major projects, and mentored junior developers; my selected work includes object detection with Mask R-CNN and a real-time Note Keeper with React and MongoDB.
