About

Alex and I started ShapeScale. It scans fat, muscle, visceral fat, and body shape in photorealistic 3D, so you can visually see what's changed rather than just a number on a scale. I've shipped websites, web apps, Android/iOS apps, custom e-commerce solutions, agentic automations, MCPs, skills, agent runtimes, plus my personal automation workflows. Most of those repos are private, and the skills and MCP servers below are the public part. Upstream, I contribute to OpenClaw, the Codex app server, and Lobster in the OpenClaw ecosystem, plus the MCP TypeScript SDK, podcastfy, and Firstmate. Most of the code is Python and TypeScript, with Node and Postgres underneath, JavaScript in the web apps, and Go, Rust, Kotlin, or Swift when a project calls for them.

Work highlights

  • ShapeScale has >1K business customers across North America. We went through Y Combinator and Stanford StartX.
  • I founded Phonejoy, the mobile handheld that turned your phone into a console, way before things like Steam Deck made it cool. :-)
