I am building an end-to-end marketplace dedicated to motor-trade services where garages, mechanics and related vendors can list their offers and customers can seamlessly book them. The website and the iOS/Android app must share exactly the same functionality so that a user can switch devices without losing any features or data. Core workflow • Service booking: customers browse available workshops or mobile mechanics, choose a date/time, confirm, and receive real-time status updates. • Customer reviews: once work is completed, the system prompts verified reviews that are displayed publicly to help the next buyer decide. • Loyalty account: every booking feeds a points-based wallet that the user can later redeem for discounts or extras. I expect a clean, modern UI, an intuitive vendor dashboard, secure authentication, card/mobile wallet payments, push/e-mail notifications, and a scalable back-end with an API that both clients consume. You are free to recommend the tech stack (for instance Flutter/React Native paired with a Node or Laravel API), as long as the final deliverables include: 1. High-fidelity designs approved before development. 2. Responsive web application. 3. Published iOS and Android apps carrying the same feature set. 4. Source code, documentation, and a short hand-over session. 5. Successful deployment to my hosting and the app stores. I’ll provide branding assets and copy; you’ll handle the rest from architecture through testing. Proposals that outline milestones for design, MVP, beta, and final release will stand out.
