// ABOUT ME

AI Engineer and Researcher

Based in Indore, India.

I'm a BS-MS graduate from IISER Bhopal with a strong base in EECS. My work spans sensing, AI, and real-time systems. I'm currently building sign-language translation avatars using deep learning, motion analysis, and 2D/3D diffusion models.

With a passion for bridging the gap between AI research and real-world applications, I've worked on gesture recognition, embedded systems, and avatar-generation pipelines for real-time communication. My journey from electrical engineering fundamentals to cutting-edge AI research has given me a unique perspective on building systems that are both technically rigorous and practically impactful.
