Github Resume + Project List Blog
I am a programmer interested in all sorts of technology. I like working on open source projects, writing blog articles, and reading on the internet. I've done a lot of internships. I also like hiking, biking and playing dodgeball.

About Me

Major projects

Sometimes I learn about a topic by putting a lot of effort into a related project.


A path tracer capable of rendering photorealistic images. Supports a physically based BRDF, textures, area lights, glossy reflection, DOF, CSG, fractals and more.


A fast high quality syntax highlighting library in Rust. I continue to review PRs and maintain it. Powers two commercial products parsing terabytes of code per day.


I built a working keyboard I created with AutoCAD, laser cut acrylic, custom firmware, and hand-soldered electronics.


An IOS app for long term personal finance simulation. Instantly updates a visualization of your entire life’s financial future while you manipulate inputs.

The Open Turing Compiler

An LLVM based compiler for Turing as well as a Qt-based IDE and a simple drawing library.

Algorithm Design

I like working on algorithms and then documenting them in long articles with diagrams.

Tree diffing as path finding

I wrote a detailed article about a tree diff algorithm I designed based on viewing the dynamic programming problem as path finding and applying A*.


At Google I worked on a novel Conflict-Free Replicated Data Type for synchronizing text editing across devices, and wrote a detailed document about my work.

Data exploration web apps

I make small fun web apps for exploring data.


A Rust web app for finding spurious correlations in 390k time series data sets. Uses custom optimized rendering, correlation and serialization code for instant responses.

Rate With Science

I extracted the link graph of Wikipedia into a 600MB binary file with a custom format designed for fast path finding in memory.


An exploration tool for long term financial market data written in JavaScript with a custom canvas graph widget allowing for navigation of hundreds of years of data.


I like writing articles about things I've learned and done.

DEF CON Qualifiers CTF Writeups

Explanations of my solutions to all the fun challenges I worked on in my first major CTF contest. I also wrote one about the DEF CON 26 Finals.

Things I've Learned Doing Internships

I wrote about how the way I think about what makes for a good job has changed over the course of several internships.

My Text Editor Journey

I wrote about my journey using TextMate, Sublime, Vim, Spacemacs (Emacs), Atom and eventually being happy with Sublime and what I learned along the way.

Stuff I've Done

This is a list of the things I have worked on and am currently working on. It is in kind of chronological order. I will try and write down all the things I have worked on. Unfortunately I don’t remember many of the things I worked on in years gone by.
