About

Mechanical Engineer turned Software Developer

I have a background in mechanical engineering and robotics through the University of Texas at Austin where I received my bachelor's degree. As an undergrad, I became extremely interested in software development which lead me to minor in computer science.

After graduation, I set out to fully transition into the field of software engineering by enrolling in a computer science master's program at Georgia Tech. Artificial intelligence and machine learning are the fields that I gravitate towards the most. Additionally, my most recent roles have been in the realm of data and data science engineering.

What other hobbies do I have?

I'm an avid traveler and martial arts enthusiast. I enjoy training Brazilian Jiu Jitsu and Muay Thai regularly. I also love to cook and play guitar.
