About 2020-03-14
I’m a Haskell and Emacs enthusiast with a very small mechanical keyboard hobby. Once upon a time, I studied physics at Columbia. I’ve just finished a degree in Music Technology at NYU with Brian McFee and currently work at Lantern. In my other life, I’m a violinist and conductor, but you can find out all about that on my other website or my youtube channel.
