Backend for a peer-to-peer lending marketplace with Bitcoin collateral

What it is

Bitraise is the startup where I work as a Blockchain Developer. It is building a marketplace for loans between individuals: the borrower locks bitcoin as collateral, and the loan itself is advanced and repaid in USDC. Put in one sentence, the idea is that someone can put the bitcoin they hold to use without selling it, and that the lender lends against real collateral rather than against a promise.

My work is on the backend: the part that carries a loan through its lifecycle and handles what happens around the collateral.

It is a startup still in its private phase, and the technical detail is under confidentiality — so this page deliberately stops at what is public: no architecture, no design decisions, no numbers. What is mine to tell is the method. The way of working with AI agents behind verification gates that I describe in AgenticPromptMethod is something I introduced here, on a real team, with code that ships.
