Full Stack AI Application Developer
Building intelligent web apps powered by AI & LLMs.
I'm a Full Stack AI Application Developer who is always curious about Artificial Intelligence — how it works, and how its applications do such incredibly amazing things. I turn that curiosity into fast, reliable web apps powered by LLMs, Machine Learning, Python and React.
(01)About me
Most developers only look at code. I look at what that code does for your business.
I'm Sumit Baweza, a full stack AI developer from India who builds intelligent web applications with Python, React, LangChain and large language models (LLMs). My path into tech isn't the usual one — and that is exactly what makes my work different.
I graduated in Physics, which trained me to break complex problems down to first principles. I then spent two years as a Manager and Accountant at a distributor agency, running inventory, staff, daily books and profit & loss reports. I learned how real businesses work — and where the right software can save them hours every single day.
My curiosity about technology never switched off, so I chose to build my career in it. I earned the IBM AI Engineering Professional Certificate on Coursera, covering machine learning, deep learning and neural networks with Keras, and building AI applications with Python. Today I build complete products: clean React interfaces, solid Python and Express backends, PostgreSQL and Supabase databases, and LLM-powered features such as retrieval-augmented generation (RAG).
AI moves fast, and I move with it. I keep up with new models, frameworks and best practices so clients get modern, practical solutions instead of yesterday's approach. I work remotely with clients and companies anywhere in the world.

All-in-one business management web app for small gas agencies
Replaces paper registers and scattered spreadsheets with one simple dashboard. Designed from my own first-hand experience managing operations and accounts at a distributor agency.
Upload any document and get instant, accurate answers from an LLM
A RAG-powered web app: users upload PDFs and documents, then ask questions in plain language. The AI answers using only what's inside the uploaded content.
Helping patients and practitioners understand prescriptions and treatment
Patients upload their doctor's prescription and ask anything about their medicines and treatment in simple language. Medical practitioners get a fast reference assistant. Built to support — never replace — professional medical advice.
