Build the Bridge

Goal: Build the core product from start to completion so the platform can process a live service transaction end-to-end.

This initiative covers every piece of foundational functionality in the service journey — from the public marketing site where vendors sign up, through to expert payment processing when a milestone is delivered. No live revenue is possible until these projects ship.
