I’m a freelance Full-Stack Developer, working on client platforms including BellyBasket, a multi-role quick-commerce platform with ordering, delivery tracking, and sales analytics. I integrated Razorpay, Firebase OTP, JWT, and SMTP.

For AVA Schools, I developed a role-based preschool management platform covering attendance, homework, timetables, student progress, and parent-teacher communication, with authentication and subscription payments.

I also built DocLore, a RAG-based document Q&A system that processes PDFs and returns source references with generated answers. It uses LangChain, FastAPI, NVIDIA-hosted models, and MongoDB.

My other work includes a YOLOv8 and OpenCV license plate detection system with a FastAPI backend and React.js frontend. I’m currently engineering a hotel operations platform for reservations, dynamic pricing, and OTA/channel synchronization.
