The work here is real; the polished public case studies are not done yet.

For launch, this page is a field guide to the projects I spend time on. Deeper write-ups will follow once they are genuinely useful.

    Marginalia

    react electron openai typescript

    Document review in most tools is passive — opening a file leaves no durable record. A version-aware reading workspace where review is an explicit lifecycle: annotations, highlights, voice segments, and transcripts captured as a structured, append-only record. React + Vite frontend, Electron shell for IPC-backed filesystem access, OpenAI integration for narration and transcription, slash-command navigation, and Markdown export. Runs in browser, Docker, and Electron modes.

    crimsonearth-ai-runtime

    typescript mcp ai runtime

    AI configurations drift across tools, producing inconsistent agent behavior when moving between Copilot, OpenCode, or Gemini CLI. A portable runtime package spanning 3 AI platforms — reusable instruction sets, durable skills, tool adapters, design doctrine, and machine-safe configuration boundaries — with non-destructive startup self-checks to detect drift without mutating local state.

    crimsonearth-kb

    sqlite go mcp obsidian

    Repeated raw search across a personal knowledge vault is slow at agent speed. Two complementary tools: a local KB MCP server with SQLite-backed full-text indexing and structured retrieval commands over a multi-hundred-note Obsidian vault; and a Go-based journal MCP/CLI for daily entry management — giving agents a fast, reusable retrieval surface without raw file access.

    TokenFlow

    typescript firebase cli

    A family token economy app: per-user interest calculations, atomic Firestore transactions for award and spend operations, birthday detection with automatic bonuses, and a full command surface via Commander.js. Ran in production for two years as a real household tool. Primary vehicle for learning real-time database design and Firestore transaction patterns.
