About Me

Why Data & AI, and A Little About Me

I am a driven problem-solverwith a strong foundation in computer science and a relentless curiosity for uncovering insights from complex datasets and ambiguous problems with a track record to prove my success.

Outside of school I love to play sports like basketball and golf as well as travelling & hiking. I also have been playing the piano for the last 12 years and enjoy playing and improvising in my free time.
