Full-Stack Developer (Next.js + Supabase + Stripe) — MVP for Family Keepsake App

PassDown (c) is a web app that helps families organize and pass down keepsakes and heirlooms with dignity — documenting an item's story, photos, and who it should go to, and letting family members express interest before decisions are made. The full product design (UI/UX) is already complete — every screen has been designed and is ready to hand off as a working reference. I need a developer to build the real, functioning backend and connect it to these designs. This is NOT a design job — it's an implementation job.
