Backend developer and UX/UI designer. I build tools for AI agents that pay for things: CLIs, SDK clients, verifiers, and the screens people use to check what an agent did.
Based in Mexico.
- CLI commands for x402 payments:
payandserve(#62), adoctorpreflight diagnostic (#59), and an offline audit-CID and Ed25519 attestation verifier (#60). All merged. - SDK: a WebSocket signals client that reconnects on its own (#61, merged), and a one-click "Deploy to Vercel" template for an x402-protected API (#58, merged).
- Trustless Work: a use case for a direct x402 payment without escrow, verified with a live settlement, merged by their team (agentic-escrow-research#3). Two research notes are open: #12 (pre-sign policy hook) and #13 (x402 and MPP Charge on one endpoint).
- Address validation: an SDK read the chain without checking the
address first. Fixed with a signed commit
