- Campaigns generated 37 million banner views, 100,000 phone calls to Congress, 500,000 emails, and 250,000 signatures.
Founder
Created a widely read educational resource for JavaScript and Backbone.js.
Highlights
- Reached over two million unique visitors annually.
- Generated 25,000+ ebook downloads and 300,000+ YouTube views.
Front-end Developer

Awards
-
October 2014
Fight For The Future
Defender of the Internet
For my work against mass surveillance and building civic tools for digital democracy.
Volunteer
Creator & Maintainer
Open-source language revitalization platform for Aboriginal Australian languages, combining dictionaries, community recordings, translation, and speech technology.
Highlights
- Built neural TTS and ASR pipelines for low-resource languages using VITS, wav2vec2, phonemic dictionaries, and fine-tuning.
- Developed language datasets, translation experiments, evaluation tools, and an Android keyboard.
- Designed consent-first, community-governed workflows where real speaker recordings take precedence over synthetic speech.
Projects
- Alpha: A dependently typed programming language and compiler for AI learning systems. Compiles model mathematics, training loops, host code, and GPU instructions into self-contained executables without conventional machine-learning runtimes.
- JSON Resume: Founded the open standard for representing resumes as JSON. Now an ecosystem of schemas, themes, developer tools, AI job matching, and agent integrations.
- cdnjs: Co-founded one of the web's largest open-source JavaScript and CSS content delivery networks, now operated with Cloudflare.
- Donto: An evidence-first knowledge system for AI agents, built in Rust and PostgreSQL. Stores contradictory claims with provenance, bitemporal history, query-time reconciliation, and formal verification.
- llmtobinary: An experimental computing platform where language models generate literal executable machine bytes rather than source code, which are validated and executed on a custom virtual computer.
- Bode: Developing a general-purpose agent execution harness for persistent sessions across web, CLI, and local development environments.
- Prove2: An experimental mathematical reasoning platform connecting ideas, Lean 4 formal proofs, theorem libraries, and AI agents.
- TPMJS: Tool Package Manager for AI Agents. Discovers, validates, and exposes npm packages as tools through MCP, SDKs, and command-line interfaces.
- Blocks: A semantic validation system for AI-generated code, using domain specifications to detect inconsistencies and implementation drift.
- Toiletpaper: An adversarial research-paper replication engine that extracts scientific claims, constructs evidence graphs, runs independent checks, and records reproducibility verdicts.
- Omega: An AI-powered Discord agent with 80+ tools, multi-database memory, code execution, and autonomous improvement workflows.
- llm-benchmark: CLI for using language models to optimize functions, validate functional equivalence, and benchmark implementations across languages and providers.

Thomas was hired as a lead developer and, upon the leaving of our co-founder took over as CTO of Earbits. Thomas is, hands down, one of those A Players you hear of companies dying to hire. He is incredibly smart, not just at code but about everything from classical music to Chinese language and culture. Thomas is great to work with and, as a well established contributor to open source projects and several successful ventures, commands the respect of engineers at all levels. I would suggest doing anything you can to have him on your team.
I've had the great pleasure of working with Thomas for the past three years at Earbits, and on a few side projects. Two years ago our CTO left on a moment's notice, Thomas saved our company by quickly stepping up to fill this role. He has been with our company through thick and thin and made serious personal sacrifices in order to help the company during tough times. He is a phenomenal hacker and a true team player. Highly recommended!
Thomas is an extremely talented engineer with a very broad range of skills and experience. From being a thought leader in the front-end community via backbonetutorials.com and cdnjs.com, to designing and implementing the API for cdnjs.com, working with Thomas has been fantastic learning experience. Thomas is truly a full stack develop, and his work output is incredible. If there is any opportunity to work with Thomas, I take it. He is the definition of an A player.
