We are looking for an experienced full-stack developer or a small, efficient team to build a modern, production-ready checkout and scan web application for an AI-based skin analysis platform. The main website runs on Framer and serves as a marketing and SEO platform. The functional web app will be built separately (e.g., app.domain.tld) and handle all core features: image upload, payment, user login, dashboard, and result visualization. You can review a competitor ai-derm.com to understand the functional workflow. However, that website is not modern or visually appealing – your implementation must be much more advanced in UI/UX, while the checkout flow can serve as a good technical reference. The actual skin analysis itself is not part of this job — the project focuses solely on developing the web application that manages the process around it (upload, payment, user flow, and results interface). The AI analysis is handled separately by us. Core Requirements – Guest checkout (no login required, result via email) – Optional account creation after purchase (Magic Link) – Payment integration via Stripe, Mollie, PayPal, or similar – Support for subscriptions, one-time payments, and refunds – Email notifications and secure one-time access links – Login via email (Magic Link) or social accounts (Google, Apple, X, Facebook) – Dashboard with scan history, credits, and subscription status – GDPR-compliant data export and account deletion – Drag & Drop or mobile camera upload – Client-side image quality check (resolution, focus, lighting) – Multiple uploads for full-body scans (up to 30 images) – After analysis, user marks the photo position on a 3D body model – Automatic connection to an external AI skin analysis API – Results include risk level, score, text summary, and optional PDF report – Anonymous data storage until user deletion – Consent for data use in AI training required – Admin panel for managing users, orders, scans, refunds, and logs Technical Requirements – Open tech stack (Next.js, React, Node.js, Django, or similar) – Secure, modular, API-first architecture – Integration with Framer marketing site via redirects or deep links – Hosting on Vercel, AWS, Render, or similar – GDPR-compliant data handling and storage – Use of Lovable, Bolt.new, Replit, or Cursor is acceptable, as long as the final solution is clean, secure, and production-grade Developer Profile – Experience building full-stack web apps (AI, SaaS, or HealthTech preferred) – Strong authentication experience (OAuth, Magic Link, Social Login) – Solid understanding of modern payment APIs – Excellent UI/UX sense with focus on modern, AI-inspired design – Attention to performance, security, and maintainability – Fluent in English or German Timeline – Development time: 1 week – Functional MVP expected after 5 days – Long-term collaboration possible for future optimization and scaling Application Please include: – Portfolio or examples of similar projects (AI, SaaS, HealthTech) – Brief description of your proposed tech stack – One-week implementation plan (milestones) Goal: Build a separate, production-grade web app with a clean, modern AI interface, seamless checkout, and an intuitive dashboard – functionally inspired by ai-derm.com but significantly more modern, faster, and user-friendly, integrated with the existing Framer marketing site.
