/about.md

15 years shipping systems that don’t blink.

Senior engineer at Quicknode building blockchain RPC and developer tooling used across the crypto ecosystem. I like things that are fast, small, and a little weird — x402 payment rails, agent arenas, raw-transaction sleuthing, healthcare dashboards that have to clear HIPAA. AI is changing development daily; the work now is finding the safe new tools that level up the LLMs. A lot was possible before; anything is possible now. If you're not using this day-to-day, you're falling behind.

cat x402-rails/README

Open-source backbone infrastructure for x402 — programmatic HTTP 402 settlements between AI agents and the services they call. Per-request stablecoin payments without an account, an invoice, or a tab. Free for anyone to drop in.

cat x402-payments/README

Open-source SDK that lets a Node or Next.js endpoint quote a price, settle it on-chain, and serve the response — turning any function into an instantly-monetizable agent service. Install, wrap your handler, ship.
