About this Gig

The future of the internet is powered by AI agents that can discover services, pay automatically, and access APIs without traditional billing systems.

I help startups, SaaS companies, AI builders, and Web3 projects integrate the x402 protocol into their applications, enabling secure, pay per use payments with stablecoins.

Whether you're building an AI product, MCP server, developer API, or autonomous agent platform, I can implement scalable payment infrastructure that supports machine to machine transactions.
