The Human Behind the Code
I'm a recent graduate in Electronics and Communication Engineering with a strong passion for Artificial Intelligence, Machine Learning, Large Language Models (LLMs), and Software Development.
Throughout my journey, I've worked on diverse projects spanning AI-powered applications, Retrieval-Augmented Generation (RAG) systems, document intelligence, automation tools, and modern web development.
My research experience includes developing machine learning models for real-world applications, including agricultural intelligence systems. One of my research contributions was recognized with a Best Paper Award, reflecting my commitment to combining research excellence with practical impact.
My goal is to contribute to innovative projects that create meaningful value and solve real-world problems through technology.

What People Say
Ujjwal demonstrated exceptional research aptitude in developing our edge-AI crop disease detection system. His ability to bridge deep learning theory with practical edge deployment is remarkable for a student at his level.
As Secretary of CTRC, Ujjwal organized some of our most impactful technical workshops. His leadership style combines technical depth with genuine enthusiasm for mentoring fellow students.
Working alongside Ujjwal on AI projects, I was impressed by his end-to-end ownership — from designing RAG pipelines to shipping production APIs. He thinks like a product engineer, not just a coder.
