I have a fully built, working React component (~1,100 lines) for a professional sustainability assessment tool. All the scoring logic, user interface, interactive charts, and intelligent recommendation engine are complete and tested. I need a developer to turn this into a hosted web application with user accounts and basic admin features.
WHAT EXISTS: — Complete React JSX component with all tool logic working — Technical specification document with architecture and data model — Clear requirements for what to build
WHAT I NEED YOU TO BUILD:
1. Wrap the existing React component in a Next.js application 2. User authentication (email/password sign-up and login) 3. Simple admin panel where I can create "workspaces" (one per client) and "projects" (assessment exercises within each workspace) 4. Participants log in → see their workspace's projects → select one → complete assessment 5. Auto-save progress on every step (so users can close and return later) 6. On completion, user enters an email address → receives a branded PDF of their results 7. Deploy to Vercel or similar with my custom domain 8. Responsive design (desktop + tablet) 9. Cross-browser (Chrome, Safari, Firefox, Edge)
IMPORTANT: The core React component and its scoring algorithms must NOT be modified. Your role is to build the application shell around a working engine, not redesign the engine.
REQUIRED SKILLS: — React / Next.js (strong) — Supabase or Firebase (auth + database) — Server-side PDF generation (Puppeteer or similar) — Transactional email (Resend, SendGrid, or similar) — Vercel/Netlify deployment — Responsive CSS — Clean, production-quality code
NICE TO HAVE: — Experience building SaaS or tool-based web apps — Experience with role-based access control (admin vs participant)
TO APPLY: Please share: 1. Your portfolio or 2–3 examples of similar projects (especially tools, dashboards, or apps with user accounts) 2. Your estimated cost and timeline 3. A brief note on which tech stack you'd use and why
I will share the full specification document and working React source file with shortlisted candidates. Payment: 30% upfront, 40% at first working demo, 30% on final delivery.
