Senior front-end engineer | React, TypeScript, and applied AI
I turn complex data and workflows into usable web applications. I've programmed professionally since 1997, and my recent work spans interactive front ends, small local AI models, browser tools, and the infrastructure that runs them. I'm based in Front Royal, Virginia and interested in senior front-end engineering and AI application roles.

Local Agent Lab | Portable AI workspace Built a private React and TypeScript AI workspace for chat, code, images, and audio. Runs models in the browser or on a local Ollama server, so it works offline and conversations never have to leave the device; API providers are optional. Projects stay in a folder or on a removable drive. Live demo · Source · More details |

Ghost Jack | Eyes, ears and a mouth for AI agents Built a local bridge and cyberpunk control deck that gives people and AI agents eyes, ears and a mouth through a $2 thrift-store pan/tilt camera, with no cloud app. Reverse-engineered its sign-in, live RTSP stream, pan/tilt, night vision and speaker (found through the vendor's old Flash engine), with recording and a three.js aiming model.

Crystal-9 | Tiny MoE for 8-bit hardware Redesigned a sparse MoE tic-tac-toe policy for a 13-token vocabulary and tight memory budgets. Released a 46,299-byte packed INT4 artifact for a custom local runtime, with zero policy misses across 294,778 legal histories. A compact adaptation powers Crystal Palace 9 on the C64.

Falken-9 | A neural network designed for the C64 Trained a mixture-of-experts tic-tac-toe model for the Commodore 64 from the start: width 8, four experts with top-2 routing and exact integer 6502 inference in a 5,195-byte model that stays in RAM. Crystal Palace 9 now plays a complete AI-vs-AI game in just over a minute, with a research report that probes the network. Live demo · Source · Hugging Face · Research report · More details |

Crystal Palace 9 | AI on 8-bit hardware Built a Commodore 64 tic-tac-toe game whose AI moves come from a real neural network running in 6502 assembly, with a command-room interface in 8 x 8 multicolor graphics. Now powered by Falken-9, a complete AI-vs-AI game takes just over a minute, down from about 20 with the original Crystal-9 weights. Source · Video · More details |

Palace-9 | Local model inspection A playable tic-tac-toe lab pairs a deterministic controller with a compact MoE model trained from scratch. It uses the Qwen2-MoE architecture for Ollama and llama.cpp compatibility without a custom fork; the browser inspects checkpoints locally.

sandbox-kernel | A small bare-metal kernel for your own OS Built a small bare-metal kernel for the Raspberry Pi Zero W that loads your own operating system as one user-mode program from the SD card. It has A/B kernel slots with trial boot and confirm, recovery to a diagnostic program, a POSIX-style ABI, an e-ink status panel and USB development commands. Game-Maker OS is the first OS built on it. Source · The guide · Game-Maker OS · More details |

Game-Maker OS | DOS Game-Maker games from the SD card, on a Pi Zero W Built an operating system that turns a Raspberry Pi Zero W into a Game-Maker machine. It boots with a castle splash to a game library on a TV, with category tabs, demo previews, saves and high scores, and plays the games' original DOS files from the SD card. It runs on sandbox-kernel; an experimental QuickJS layer runs small JavaScript apps. Source · sandbox-kernel · More details |

Game-Maker Pocket | DOS games in your pocket Built firmware that plays Game-Maker: Sandbox Edition games from their real DOS files on cheap ESP32 touch-screen boards, with a microSD library, touch and stylus controls, a settings screen and a first-start display setup. A GitHub Pages install page flashes a board from Chrome or Edge. Web flasher · Source · Game-Maker OS · More details |

I volunteer with local history and library projects, started a LEGO users group, and sometimes perform as a clown. I like projects that connect technology with something people can actually use, explore, or enjoy.
