• BookmarkIndexer

  Search your browser bookmarks by what the pages say, not just their titles. Loads each page in a headless browser and indexes its text for hybrid vector and keyword search, all on your own machine. ASP.NET Core API with a Next.js UI, Postgres with pgvector and Ollama.

• Claude Code rules for .NET

  My guidelines for Claude Code on .NET projects, so the code reads like an experienced developer wrote it by hand: less code, few types, thin controllers, surgical changes.

• Antigravity OS

  A toy 64-bit operating system in C for x86_64 PCs and the Raspberry Pi 3, with preemptive multitasking, an ext4 filesystem, a self-installer and GW-BASIC, the first language I used. On the Pi it boots straight into Paratrooper, played with an Xbox controller over its own Bluetooth LE stack. Built with Antigravity CLI and Gemini, later Claude Code.

• PersonalAI

  A self-hosted AI agent platform. Chat with local or hosted LLMs that use tools and a Docker sandbox, and schedule reusable skills to run as agents. ASP.NET Core API with a Next.js UI.

• Prince of Persia, ported to C#

  Rebuilt from the original source, disassembly and public notes by an LLM working on its own, judged only on whether the game plays right.

• Paratrooper, ported to C#

  The 1982 DOS version of Paratrooper, ported the same way.

• DOSBox control skill for Claude Code

  Lets Claude launch DOS programs in DOSBox, take screenshots, send keystrokes and close the window, through a small local ASP.NET Core API.
