How Vaibhav Turns
Ideas Into Intelligent Systems

A combination of computer science fundamentals, machine learning, AI engineering, and product development.

The mind behind
the models

I'm Vaibhav Gupta, a B.Tech Computer Science & Engineering student at Raj Kumar Goel Institute of Technology (RKGIT), graduating in 2028.

My work focuses on machine learning, deep learning, generative AI, data-driven applications, and scalable software engineering.

Alongside AI development, I consistently practice data structures and algorithms to strengthen problem-solving fundamentals and write efficient software.

I enjoy turning complex technical ideas into practical products that solve real-world problems.
