Hi there!

I work at the intersection of product, engineering, security and cryptography.

I am the co-founder of Footprint, the last identity verification form you'll ever need to fill out on the internet! In just a couple of lines of code, Footprint lets companies frictionlessly onboard users and offload the security, vaulting, and compliance associated with storing PII.

Previously, co-founded (acquired by Akamai), to make strong authentication easy and beautiful to use for consumers and developers. We're the makers of Krypton Authenticator (now Akamai MFA). I worked on everything from building our cryptographic protocols to product design, user-experience, and iOS engineering.

Before, I spent 5.5 years at MIT. I finished my undergrad in 2015 in and my masters in 2016 in computer science + cryptography. I had the privilege of working with Shafi Goldwasser on my master's thesis, Natural Language Processing on Encrypted Patient Data.

I've been making iOS apps for 10+ years -- starting with iOS 3 back when I was in high-school! I built a number of real-time transportation apps with my dad to help commuters in Boston, for example the Greenline app.

Recent side projects
  • A simple developer utility that lets you expose your local web server to the internet with a public URL.
  • A zero-trust web app to quickly and securely send files with a one-use link.
  • sift Open-source project to sniff app network traffic on iOS.
