Contractor pay.
Protocol design.

I founded FairPay for contractor payments and Fairstudio for Web3 fantasy sports. My work spans US virtual accounts, custody-connected payouts, Solidity contracts, and UMA-backed oracle escalation.

The work.
And what went into it.

The two founder-led ventures come first. Both include the underlying system and the application people use.

Web3 & payments / focus

The rails, and the product around them.

FairPay connects contractor accounts, a company console, invoice approval, and custody providers. Fairstudio connects data validation, oracle escalation, and a Next.js PWA.

The mechanics, up close
