I build the kind of software that usually costs a subscription, and I give it away. Crypto microstructure terminals, SEC filing pipelines, agent harnesses. Open source, local-first, runs on your machine.
Philadelphia. Mostly C++ and Python, Qt on the desktop, FastAPI behind it. Most things start as a prototype and get rebuilt properly once they prove out.

Work
SentinelA crypto microstructure terminal you run on your own machine. The live order book as a GPU heatmap, footprint, TPO and volume profile layers, a DOM ladder, SEC insider overlays and server-side paper trading.
CopeNetA local stock market terminal with an AI analyst that logs every call before the outcome is known and scores it afterwards. Underneath it, my own agent harness.- CopeTech-EdgarA Python library that pulls and parses SEC EDGAR data. Forms 3, 4 and 5, 13F holdings, filing discovery, point-in-time financials. The data vendors charge for this; EDGAR is free if you can run it.
- SkyCraftA shared voxel sky island in the browser where players and two AI companions walk, mine, craft and build in one world. The server checks everything they do.
SubtextPaste a link from your phone, transcribe it locally with Whisper, run analyses through Ollama. A private web service over Tailscale and a desktop companion for editing and export.

Nothing published yet. The first posts are about Sentinel's renderer and parsing SEC Form 4 for free.

Pushing Sentinel's server and recorder. Rebuilding this site so it can hold writing. Working out what to charge for and what to keep giving away.
