I’m building practical AI applications that solve real business problems — with a focus on customer service, automation, AI-assisted workflows and digital experiences.
My background is in Customer Success and Sales, and I’m developing my skills toward the AI / AI Automation field by combining business experience with hands-on projects.
A family of live APIs that AI agents pay for per call in USDC over the x402 protocol (Base and Solana). No accounts, no API keys. All of them are listed in the Coinbase CDP Bazaar, so agents can find them on their own.
