Information About me


I am a final-year Information Technology student at Galgotias College of Engineering and Technology. I enjoy building software that lives at the intersection of intelligent design and AI-driven logic.

My core expertise is Full Stack Development with the MERN stack — crafting responsive, production-ready applications using React.js, Node.js, Express, and MongoDB. I also specialize in AI Integration, building LLM-powered features using Groq's inference API, custom AI agents, real-time token streaming, and intelligent automation pipelines.

From building an AI resume platform with ATS analysis to a real-time AI chat app with multi-model support, I love working on projects that push boundaries. My goal: ship fast, scale smart, and make AI work for real people.
