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.

  • Trained a 1.38B-parameter language model over 5.84B tokens on two H100 GPUs, averaging 247,865 tokens/sec with an Alpha-generated executable.
  • Built native NVIDIA GPU code generation, FP8 kernels, attention, multi-GPU NVLink communication, and direct driver interfaces without CUDA, PyTorch, or NCCL on the training path.
  • Developing dependent types, formal verification, and compiler infrastructure for agent-driven discovery of new algorithms and learning systems.

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.

  • 7,000+ GitHub stars across the ecosystem and tens of thousands of users.
  • 52 first-party themes, a public registry, in-browser editor, CLI, and MCP integrations.
  • AI job matching with embeddings, hybrid retrieval, and LLM reranking; improved precision at five from 0.2 to 0.8 in evaluation.
  • Maintains the schema, CLI, core libraries, jobs package, and Rust serialization tooling.

cdnjs

Co-founded one of the web's largest open-source JavaScript and CSS content delivery networks, now operated with Cloudflare.

  • Used by millions of websites and serves billions of requests monthly.
  • 10,000+ GitHub stars.
  • Helped establish a community-maintained infrastructure project that became a widely used part of the web.

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.

  • 42M+ statements and millions of evidence links, with large-scale LLM extraction and agentic-memory tooling.
  • Custom query language, predicate alignment, temporal reasoning, and provenance-aware access control.
  • 62 Lean 4 theorems proving core invariants, plus signed and reproducible knowledge releases.

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.

An experimental mathematical reasoning platform connecting ideas, Lean 4 formal proofs, theorem libraries, and AI agents.

  • Exploring machine-checked mathematical reasoning and proof-assisted AI research.
  • Developing agent-friendly interfaces for theorem exploration, proof construction, and verification.

  • Automatic npm tool discovery and sandboxed Deno execution.
  • MCP aggregation and agent tooling infrastructure.
  • Platform for building, sharing, and extending AI agents.

Blocks

A semantic validation system for AI-generated code, using domain specifications to detect inconsistencies and implementation drift.

  • Declarative domain specifications using entities, signals, measures, and rules.
  • Schema, structure, and LLM-based domain validation with actionable feedback for coding agents.

Toiletpaper

An adversarial research-paper replication engine that extracts scientific claims, constructs evidence graphs, runs independent checks, and records reproducibility verdicts.

  • Processed the Kolmogorov-Arnold Networks paper: 102 claims extracted, 24 reproduced, and 3 contradicted.
  • Combines LLM extraction, simulations, mathematical checks, and provenance through Donto.

Omega

An AI-powered Discord agent with 80+ tools, multi-database memory, code execution, and autonomous improvement workflows.

  • Code execution across 42+ programming languages.
  • Agent tooling for software development, communication, and GitHub-driven self-improvement.

llm-benchmark

CLI for using language models to optimize functions, validate functional equivalence, and benchmark implementations across languages and providers.

Joey Flores, Co-founder and CEO of Earbits, Inc.

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.

Yotam Rosenbaum, SVP of Operations, Earbits, Inc.

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!

Ryan Kirkman, Senior Software Engineer at Nerdwallet

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.
