I built BrainPick, a marketplace for hands-on know-how. Looking for volunteer testers

BrainPick is an early web product I am validating: it connects builders who need practical know-how with experienced practitioners (drivers, tradespeople, tailors, mechanics) for short remote knowledge sessions. The pilot is live with working signup and intake forms backed by a real database. I am looking for honest usability feedback: try signing up as a builder or a practitioner, complete the intake form, and report what was clear, confusing, or missing. About 15 minutes, start here: https://brainpick-kohl.vercel.app/usability.html This is a volunteer beta, no payment involved. The stack is a static front end with serverless intake endpoints, and the repo runs Playwright end-to-end tests against production in GitHub Actions daily. Feedback of any kind is welcome, including here in the comments.
