About
Thanks for dropping by! I'm currently working with Rakuten Viki, where I work on shipping performant features on their web application.
Outside of coding, I enjoy rock climbing and hiking 🧗🏻♀️🥾 A fun fact about me is that one time I almost made it to Everest Base Camp, but a snowstorm had other plans for me. I occassionally play video games on my Switch or computer, and most often you will find me on Tetris or pondering over Killer Sudoku 🎮🧩
