About Me

I’m currently pursuing my M.Tech in ECE at IIIT Bangalore. I completed my B.Tech in Electrical and Electronics Engineering from Amrita Vishwa Vidyapeetham. My academic background helped me build a clear understanding of digital design and VLSI fundamentals.

My focus areas include physical design and static timing analysis. I’ve started my internship at Samsung Semiconductor India Research (SSIR), where I’m getting exposure to real design flows and industry practices.
