Work
Things I’ve built
Robotics infrastructure, iPhone apps, research runs and live experiments. Every one a system built to keep someone safer, more included, or better informed. Pick a lane or read straight down.
Platform
PlatAtlas and the open-source robotics stack underneath it.
PlatAtlas
PlatAtlas gives agentic and physical AI work a verifiable accountability layer. Per-org consoles map what agents and machines do, sign every action, and keep a replayable record. OpenCastor is its open-source robotics edition.
OpenCastor
OpenCastor is the open-source robotics edition of PlatAtlas. A single ROBOT.md manifest, the RCAN wire protocol with Python and TypeScript SDKs, an MCP server so any LLM can drive a robot, and a public registry with the first five EU AI Act-aligned endpoints.
Robot Registry Foundation
Public identity and compliance for AI-driven robots: permanent RRNs, Ed25519 ownership proof, and the first five EU AI Act-aligned endpoints, live.
Continuon
An embodied-AI project exploring a single brain that persists across many robot bodies, with the ContinuonXR spatial-computing interface for robot control. RCAN, the wire protocol used across the OpenCastor stack, started in the continuonai org and now lives at RobotRegistryFoundation/rcan-spec.
Apps
iPhone apps on the App Store, most of them built for people who are usually left out of the brief.
Microduck Studio
Read a duck's trained policies, write motions, teach it with printed coding cards, and train it with your own picks. Every claim about what the duck can do is measured in Pollen's simulator first, pre-registered, and published with the rejections.
LiveCaptionsXR
On-device spatial captioning for deaf/HoH users in XR: captions appear in 3D near whoever is speaking, running on the Qualcomm Hexagon NPU.
HearAura
An Auracast broadcast assistant for LE Audio hearing aids and earbuds, with live on-device captions and local-network audio channels. Submitted to the App Store in 2026.
Exsiccatae
A free iPhone field journal that identifies birds by photo and by song, entirely on-device, and renders your life list as a watercolor herbarium. Submitted to the App Store in 2026.
Heat Compass
Live WBGT heat flags, work-rest guidance, and capped hydration coaching, computed from published heat-stress doctrine and audited for accuracy before shipping. iOS 1.0 submitted in 2026; an enterprise console edition lives at heatcompass.com.
Bicycle Radar
On-device vehicle detection that warns cyclists about traffic approaching from behind, with audio and haptic alerts so your eyes stay on the road. The 1.0.25 release went to App Review in 2026.
Research
Questions I ran instead of arguing, with the failures published at the same standard as the findings.
QuantumMytheme
An open-source bench where a capable model designs a quantum circuit or chip and a deterministic, numpy-only judge re-simulates and ACCEPTs or REJECTs it. The wedge for a verifiable-efficiency referee: an honest map of where machine intelligence actually gets more efficient.
Heat Protein Lab
An interactive, browser-based lab that walks you down a temperature gradient and shows, with real PDB/AlphaFold structures and rigorous prose, how proteins like HSF1 sense and survive heat. The thing I built after I built the wrong thing.
An LLM at 50 Hz
A checkable answer to a challenge posed on X: three controllers, eight terrains, one MuJoCo plant, ten perturbed starts per cell. The LLM's 50 Hz command table never stood for six seconds. The five-year-old trained policy walked up to its training limit. Every episode, script and reference is published.
Fitness Report
I graded fourteen public MCP servers on whether an AI agent can actually get work done with them. The first full pass scored none of them, because the harness caught its own tasks being answerable without the server. The refusals are the product.
FOIL
A response to Anthropic's Frontier Red Team work on multiagent systems: reordering identical inputs can invert a model's decision. Eleven pre-registered studies, two zero-dependency Python tools, and a failure record published at the same standard as the findings.
Experiments
Live pages with their own design: a globe, a tide gauge dashboard, a tier list.
Emergency Rappelling Recovery
Eight concept plates, each aimed at a different way a descent can go wrong and each with the one experiment that would decide it. No claim about what happened, and no qualified equipment.
Rebuilt from the spec
A heat-stress calculator, an MCP traffic recorder and a robot-evidence verifier, each turned into a spec, a suite that judges any implementation from the outside, and blind rebuilds in two languages. The page is the ledgers: every run, what it cost, and what the spec had to say before a rebuild came out clean.
OpenCastor × Gemma
I ran Gemma in Ollama on the same Raspberry Pi 5 that hosts my robots and held every reply to a schema built from the robot's signed manifest. Gemma 4 E4B passed 11 of 12 rover cases, all 90 guided Gemma replies were valid JSON, and a person still signs every draft before the robot's gateway decides.
Shade Map
Pick a park, a game and a seat. A bowl map colored by sun and shade, a clock you can scrub or play through the game, a whole-game view of how much of it each row spends in shade, and a seat card that says when the shade reaches you. The rim of the stands is measured from USGS lidar at 41 parks, including 19 Cactus and Grapefruit League spring training parks; the seats are measured at 20, the outfield seating at 17 of them, and assumed everywhere else, and the page says so.
Date the war
A black-and-white globe with every sourced event since 1900, a timeline you can narrow to a day, a month or a year and play forward, seven impact groups, a mobilization layer that shows what a war economy looks like before anyone calls it one, and a stress layer for food, water, oil, people and the movements between them. The page never declares a third world war. It hands you the marker.
The League
One hundred and seventy-seven countries, six tiers from Dodgers to non-roster invitee, and every country affiliated with one of the thirty franchises. A world map by tier, a club map with all thirty ballparks at their real coordinates sized by how many countries report to each, detail cards built like the back of a vintage baseball card, and a roster you can group by tier or by club. It started with one Reddit line about the Saudi military: Dodgers payroll, Angels talent.
RT Lab
Six tabs. A pairing model you can push toward 293 K, a Tc landscape computed on this site's own Raspberry Pi with the toolkit's Eliashberg solver, a second map of how much of the coupling must be hydrogen's, four published materials placed on it, starting cells for a hydride benchmark, the synthesized boron–carbon clathrate and the hydride-filled clathrate the bet cites, a Quantum ESPRESSO pipeline executed end to end on aluminium and then on MgB₂ as a reproduction attempt, six experiments with pre-registered kill criteria, and a ledger that ties every number to a source. No material is claimed. Every number is a model output or a citation and says which.
Sea Levels
A live dashboard built on public ocean data: NOAA tide gauges queried straight from the browser, an along-coast panel that watches El Niño's coastally trapped waves arrive at the gauges, the satellite altimetry record since 1993, the sea level budget, and IPCC AR6 projections, all in dependency-free SVG charts.
Downtown Miami Flood Risk
The local companion to my global Sea Levels tracker: LiDAR terrain, drainage, groundwater, and insurance records for Brickell through Edgewater, assembled into an interactive 3D visualiser, a live upstream ice monitor, and a plain-language guide, with every inferred value tagged as inferred.
Beverage Tier Maker
A drag-and-drop tier list for beverages with share links that encode the whole board in the URL, a PNG export drawn on canvas, and one obvious S-tier answer. The first page on this site with its own test suite.
Heat Threshold
A Gemini-driven, multi-agent environmental-logistics and heat-safety scheduler: WBGT risk flags, route planning, and a GO/NO-GO verdict for outdoor activity. A real working build, and the wrong answer to the question I actually cared about.
Tools and concepts
Open-source tooling and earlier concept work.
Ralph
An open-source harness for autonomous AI development: 10+ agents with deliberate context rotation, on macOS, Linux, and Windows.
Dronevade
Edge computer-vision platform for drone detection: custom YOLO models with RF and thermal fusion, designed for the field.
Farmhand AI
A concept demonstration of autonomous agricultural robotics: computer vision and edge AI for crop monitoring and livestock management.
