GBuild

Currently Building

Build anything. Smarter.

A macOS desktop app that orchestrates 12+ AI coding agents (Claude Code, OpenClaw, Hermes) from one calm, voice-first interface. Electron + a Rust sidecar over JSON-RPC, pluggable agent drivers, a whisper/Piper voice pipeline, a RAG layer, bidirectional Obsidian sync, an MCP gateway, and the "G" mascot. Marketing site live at gbuild.app; the desktop app is in private development.

Johnson Power Rankings

Currently Building

A world ranking for the 200+ mile ultra.

A data-driven, weekly world ranking system for ultramarathon runners, launching with the 200+ mile tier. A pure-TypeScript engine (course-difficulty model, iterative field strength, time-decayed weighted-mean ratings, backyard scoring) over a Supabase backend with 11 migrations, RLS on 20+ tables, 6 edge functions, and a Monday recompute cron. A Next.js web app, a separate admin panel, and an Expo mobile app. Built with my dad as the domain expert. Live in preview; public launch pending.
