Production readiness audit for Next.js, Supabase and AI-built apps: a fixed-price report with a cost per finding, then fixes for what fails. Built fast with Lovable, Bolt, Replit, Cursor or v0, and now real users are arriving? I check auth and tenant isolation, payments, data and deploys before something breaks. If the app is in good shape, the report says so and you stop there. WHO I WORK WITH Founders and product leads with a live app that works in the demo and worries them in production.
