#### About

I am a mechanical engineer with a strong interest in computational simulations. Currently focused on learning Computational Fluid Dynamics. Able to model, and make quick design changes using software tools.

I worked at Emflux Motors as a Product Development Engineer, where  I was responsible for the design of chassis and powertrain components. I am also well versed with Finite Element Tools.

Apart from this, I have three years of Formula Student experience.

This page is meant to serve as a documentation of the various projects I have undertaken and completed.
