In the past, I have interned at CDK Global (2015), worked as webmaster for the ASUW (2014), and been a teaching assistant for various computer science courses at the University of Washington (2015—16).


My interests within computer science include web development, web applications, and UI/UX design. I have also been writing my own technology-centered blog, The Thought Box, for over seven years.
