hi, i am baihao

I am currently building eval, trace, MCP, and control-plane plumbing that lets teams ship AI agents they can trust. Product-wise I build type-safe, snappy web applications with a bias toward functional programming, local-first architecture, and decentralizations. Avid follower of Parse, don't validate.

TypeScript React Next.js Effect-TS Bun Drizzle Postgres Cloudflare

Agent Infra & Dev Tools

  • pi-trust-mono - trusted control plane for pi (policy gates + trust scoring + eval checkpoints).
  • model-picker - interactive OpenRouter model picker; CLI + installable agent skill.

Past projects

I was activly building in the web3 space with exchange platforms, decentralized application, protocols, web visualizations, etc.

  • matters-forum - Web forum for IPFS-curated content with wallet auth, commenting, RSS
  • wrap-eth-arbitrum - DApp for wrapping/unwrapping ETH on Arbitrum
  • btc-tx-script - BTC UTXO transaction parser
  • atkinson-dither - Vintage Macintosh dithering vibes with web components
  • r3f-rubiks-cube - Interactive Rubik's Cube with React Three Fiber
  • yanyu - Text-to-Speech node package with pinyin audio library

If you're building agentic infra + devtools, local-first inference, or type-driven APIs - say hi.
