• Researched and documented legacy systems developed by former employees.
• Implemented hybrid on-prem/cloud backend balancing performance and cost.
• Fixed and optimized OkCupid's Boost feature.
• Delivered talks on Kubernetes, high availability, and inclusive software design.
• Developed tools for managing code across dozens of repos.
• Built automation tools to mitigate risk for code refactoring.
• Designed and implemented an international geolocation database.

Contributed open-source enhancements to JavaScript in V8/Chromium and standardized tests for Test262.

• Added internationalization features to V8's standard library.
• Contributed BigInt tests in Test262.
• Implemented trailing commas for function parameters in V8.

Architect and majority contributor for OpenArbor®, an Eclipse-based IDE in Java for developing safety-critical C/C++ applications.

• Developed a Makefile generator to unify build steps inside and outside the IDE.
• Designed a Time Map tool with Gantt charts to visualize thread and interrupt scheduling.
• Redesigned an embedded test harness in C, achieving a 10x speedup by optimizing network usage and storage.
• Created an embedded Lisp-like interpreter in C, enabling interactive control of Deos APIs.
• Rebuilt an internal source code scraper to support flexible trace tags with a command-line API.

Created an interactive client/server system to control a motor-mounted camera for high-resolution photography of entomology specimens for Arizona State University. Used Python3, C++, and Qt. [src]

Zip and unzip libraries for Node.js. Yauzl is the most popular unzip implementation on npm with 15M weekly downloads (as of April 2024). [src, src]

Contributor to the Zig programming language compiler and standard library, and a board member of the non-profit Zig Software Foundation. Designed and implemented much of the original grammar/parsing, expression semantics, C-to-Zig transpiler, and more. Made significant contributions to the JSON support in the standard library. [src]

Yet another rotate-tiles-to-connect-loops game. Mobile friendly! [src]

Alternative to git submodules that avoids all the headaches. This is the most polished of my projects to enhance/replace git with a better version control system.

A music player server with a web-based user interface written in JavaScript for Node.js and the browser. Co-authored with Andrew Kelley. [src]

A clone of Snakebird by Noumenon Games for the browser featuring a level editor to encourage community-made levels. [src]

Rogue-like hack-n-slash game inspired by Nethack originally written in C++ using SDL, then rewritten in Zig. [src]

Multiplayer board game and card game simulator for the browser. [src]

An exploration of different maze generating algorithms on different topological spaces. Has some statistical analysis built in. [src]

Checks for and fixes whitespace mistakes like trailing spaces, mixed newline styles, and mixed indentation styles. Written in Python. [src]

Quick and easy file sharing client and server written in Python for the command line. [src]

Java-like language that compiles to Java .class files and runs in the JVM. [src]

A statically-typed language with full type inference. Uses LLVM to output native machine code. [src]

A simplified MIPS simulator and debugger featuring preemptive scheduling. Debugger supports go, step, setting breakpoints, and showing source code and registers. [src]

Wraps /bin/svn and decorates and formats the output with terminal color. [src]

REPL-enabled interpretor for performing mundane matrix operations to check my work in Linear Algebra class.
