SaaS Bug Fix and Technical Audit - React / Node.js / Railway / Vercel

I have a working web app called Clarity Ops Method, a 10 stage AI-assisted operational problem solving tool. Built with CTO.new, frontend on Vercel, backend on Railway, codebase in GitHub. I need two things from you. Fix a bug and give me an honest technical assessment. The Bug: User inputs from the onboarding flow are not populating into the stage deliverable outputs across all 10 stages. Deliverables show placeholder text instead of the user’s actual answers. Likely a single data flow or state management issue. The Assessment: Answer these in plain English. What is the quality and structure of what has been built? Can it handle multiple users simultaneously? Can the framework support additional methodology modules as separate products? What are the three most important fixes needed before commercial launch or white labelling, and what would each cost and take to fix? I will provide GitHub access, the live app URL, and a walkthrough of the intended user flow. I need a fixed price quote for the bug fix, a written plain English assessment, and honest feedback. Looking for someone with SaaS experience, React or Next.js, Node.js, and Railway or Vercel experience who can communicate clearly with a non-technical founder. Do not apply if you plan to outsource or cannot start within one week.
