Software engineer or researcher with a passionate team of hackers that respect users' freedoms, strive to innovate, embrace challenge, and seek to make a positive social and cultural impact.


I am a self-driven and passionate hacker with over twenty years' experience in many areas of software development and computer science. I am an activist for user freedom with a focus on user privacy and security. I seek to collaborate with and learn from an innovative team of hackers that are equally passionate about their work and will challenge my wide range of skills and interests. I focus primarily on compiler construction and the creation of declarative domain-specific languages and abstractions to simplify development and improve the correctness of complex systems. Some of my personal interests beyond compiler construction include programming language history and theory, formal methods, logic and type theory, cryptography, philosophy and ethics, and writing.

The focus of my research in recent years has been pursuant to addressing problems of practical user freedom—to make various aspects of freedom in computing accessible to more users in concrete and tangible ways that are meaningful to them beyond abstract principle and philosophy.

A prospective employer must be willing to use and write free software, and be positive toward software freedom and the free software movement.


Ryan Specialty (formerly LoVullo Associates, Inc.)
March 2009–Present
Principal software engineer. Designs, develops, and maintains compilers for domain-specific languages (DSLs); application frameworks; server software; and web applications for an Excess and Surplus Lines Insurance Agency. Most work is pursuant to developing complex online systems to provide comparative insurance quotes from thousands of conditional inputs and providing a suite of development tools and DSLs to support those systems. Responsible for developer training and knowledge transfer through design discussions, documentation, peer programming, and code review. Involved in every aspect of the development process and many decisions regarding the technical direction of the organization.

Freelance Web Developer
March 2006–March 2009
Worked as a freelance web developer primarily through RentACoder.


Listed here are both my own projects and those to which I have made notable contributions. I have many miscellaneous projects and scripts that are not listed here; see my Projects page for a full list.

This system was developed at LoVullo Associates and Ryan Specialty to handle the complexity of comparative insurance rating systems. It is a domain-specific language (DSL) that is itself a metalanguage through the use of templates, encouraging the creation of specialized sub-DSLs. TAME processes only numerical input and output, with conditional logic driven by higher-order predicates. Calculations and predicates are written declaratively without regard for order of execution. The system is used to define tens of thousands of calculations and predicates across thousands of inputs.
TAME consists of a macro processor (implementing a metalanguage), compilers for various targets (JavaScript, HTML documentation and debugging environment, LaTeX, dependency graph output, and others), linkers, and supporting tools. The input grammar is embedded within XML, and the project was originally written in XSLT. The project is undergoing a rewrite in Rust (TAMER).

GNU ease.js
November 2010–2017
A Classical Object-Oriented framework for JavaScript, intended to eliminate boilerplate code and “ease” the transition into JavaScript from other Object-Oriented languages. Features include simple and intuitive class definitions; classical inheritance; abstract classes and methods; interfaces; access modifiers; static and constant members; and traits as mixins. Became a GNU project in December of 2013.
GNU ease.js was created as a personal project to simplify development of a project at LoVullo Associates, and supports ECMAScript 3 browsers (as far back is IE 5.5). Implementation details and rationale are documented extensively in the manual and comprehensive test cases. See also my paper Classifical Object-Oriented Programming with ECMAScript. Copyright has been assigned to the Free Software Foundation. I no longer maintain this project, and recommend TypeScript in its place, which provides most of ease.js' features and is a compiler rather than a framework.
  • JavaScript (ECMAScript 3, ECMAScript 5)
  • Shell (POSIX, Bash)
  • Autotools (Autoconf, Automake)
  • Texinfo
  • AWK
  • Sed
  • LibreJS-Compatible
Liza Data Collection Framework
Data collection and processing framework developed at LoVullo Associates and Ryan Specialty to handle the collection and processing of thousands of complex conditional inputs for online comparative rating systems. Programs are defined using a declarative DSL which compiles into JavaScript. The client is a web application which shares code with the server using Node.js. It also contains its own tools for debugging and introspection.
This project integrates tightly with TAME for its classification system and depenedency analysis.
  • Rust
  • XSLT 2–3
  • JavaScript (ECMAScript 2016)
  • Node.js
  • Shell (Bash)
  • Autotools (Autoconf, Automake)
A self-hosting Scheme compiling into JavaScript. The project is incomplete, but it does successfully bootstrap a very limited Scheme-like Lisp.
  • JavaScript
  • Scheme
  • Node.js
GNU Guix
October 2016–Present
Improvements to guix environment container support; package contributions.
  • Guile Scheme
  • Shell
GNU Screen
November 2013–July 2015
Refactoring and cleanup of window message system and related code; creation of supporting abstractions; introduced unit tests.
This began as a cooperative effort between myself and Amadeusz Sławiński to resurrect the stalled development of GNU Screen. Amadeusz is now a co-maintainer of the project and my changes have been merged upstream.
