About Niraj
I’m Niraj Kumar, a passionate BS Data Science and Applications student at IIT Madras, currently in my 3rd year. With a strong academic foundation and hands-on project work, I’m actively exploring how AI, data, and web technologies can come together to solve real-world problems.
I’ve worked on projects like a RAG-based chatbot using LLM and web apps using Flask, VueJS, and Redis. These experiences deepened my interest in building smart, user-friendly tech solutions.
As a Regional Coordinator (RC), I’ve led multiple student offline meetups with various events. I also mentored peers in building initiatives like the Cybersecurity and AI Club, GATE Prep Club, and Web Developer Club for the Techies, promoting collaborative learning and leadership.
Outside academics, I enjoy writing poems, playing badminton, and sparking tech discussions. I bring creativity, curiosity, and teamwork into every space I’m part of.
