I am an Internet Swiss Army Knife.


I tend to stay near the creative side of tech; the places exploring things that aren't well understood yet. I like being the person who writes the first line of code, and I'm willing to try new things while I do it. Technology makes it easy to jam on ideas with small groups of people, and I embrace this.

I have worked with Harvard Law School, Calypso, Bear Stearns, which became JPMorgan, Johns Hopkins, The Robin Hood Foundation, EXFM (acquired by Microsoft), Venmo (acquired by PayPal), VHX (acquired by Vimeo), and I used to run a consultancy called J2 Labs.

I have also been an investor / advisor for Socratic, Sunrise (acquired by Microsoft), VHX, Lua, Thinglink, Chromatik, and some others.

I currently spend my time working with teams in machine learning & devops.


I can program in a bunch of different languages. Lately it's been Flutter & Python.

I like writing open source software. I sometimes start open source projects too. Of all the projects I've started, Schematics is my favorite. It is something like a type system for Python. Brubeck was a concurrent server framework with strong opinions on web serving, concurrency, data modeling, and messaging. And Micro Army is a tool I made for testing Brubeck's performance. It works by instantiating a few hundred AWS Micros to flood some URL and report back the performance.

One of the more rewarding aspects of open source is learning where your work turns up. You've used some of my work if you code trading algorithms on Quantopian, read Huffington Post, wear Warby Parker sunglasses.

I also have a computer science degree from Northeastern University. And I was in the first batch of Recurse Center, formerly known as Hacker School.


You might know about some of the communities I've created: Hack && Tell, Brooklyn Swift, and Dumbo Tech Breakfast.

I'm on Twitter. I tend to tweet about tech, music, infosec, and I use Twitter to learn about my side passions, like history and economics.

I sometimes post code on github, though I was more active in open source back when I ran J2 Labs.
