OFF THE MAIN THREAD
Everything here was built for real, but none of it is clinical work. Hardware, iPhone apps, browser vision, agent skills, and one piece of executable science fiction. It lives on its own page so the radiotherapy work stays legible.
Builds & prototypes
Each one has code, build files, or a running demo, and a note on what it does not prove.
Executable science fiction · Distributed systems
Mission control for a star-sized distributed system. A deterministic browser simulation lets an operator stress 10,000 autonomous solar collectors with communication loss, thermal limits, debris, demand spikes, and cascading failures.
Local AI · Smart glasses · AWS Strands
I built a consent-first smart-glasses agent that interprets selected moments on the phone, minimizes what leaves the device, and proposes one explainable next action without silently taking it.
Agent skills · Active recall
AI wrote the code. Now make it yours. A Claude Code and Codex skill that turns a real Git diff into one-question-at-a-time lessons and code-grounded project interview practice.
Local vision · Resale
SellShot and PackCheck analyze product-photo quality and packaging changes entirely inside the browser, without uploading images to a server.
Hardware · Resale
A repeatable eight-angle photography turntable for secondhand products, including CAD, STL files, ESP32 firmware, iPhone control, and a complete BOM.
Plant tech · Fabrication
A propagation cabinet that records rooting and acclimation. The HOME 12 and PRO 48 studies include build guides, costing, CAD, and explicit safety boundaries.
iPhone apps
SwiftUI applications built around cameras, QR codes, Bluetooth devices, labels, and local records.
SwiftUI · Vision OCR · Camera
A local-first move-in and move-out evidence app. It reads room names from a floor plan, guides both parties through the same nine views, compares matched captures, records signatures, and exports a PDF report.
SwiftUI · Local-first operations
An iPhone inventory, QR checkout, and return-inspection app for small rental operations. It records kit components and condition photos, prints AirPrint or ZPL labels, and stores data locally.
Swift · BLE · Camera
An iPhone controller that coordinates an ESP32 turntable, lighting, homing, weight readout, and an eight-angle product photography sequence.
