Hi, I'm Mukund 👋

I like to build useful things

MS

Currently a Member of Technical Staff at Character AI. Previously co-founder and CTO at Quilt Labs. I did a PhD in Machine Learning at NYU, interned at Goldman Sachs, and  graduated from Cornell with a degree in Computer Science. This website is a collection of random projects, mostly in blog form.
