I am building a services-booking marketplace that brings four distinct categories under one roof—professional services, regular household services, event booking, and restaurant table reservations. Phase 1 focuses on a responsive website that serves three audiences: end-users, vendors, and a single super-admin. Security is a priority, so the platform must ship with multi-factor authentication out of the box. I also want a clean, modern design that loads quickly on mobile and desktop. Key requirements • User flow: browse or search, view vendor profiles, book or request a service, confirm via email/SMS, and track status in their dashboard. • Vendor flow: self-register, create listings by category and by location, manage availability, pricing, and incoming orders from a dedicated vendor panel. • Admin panel: full CRUD over users, vendors, categories, commissions, and content, plus analytics and manual booking override. • Core features: role-based access, real-time notifications, review & rating system, built-in wallet or payment gateway integration, and SEO-friendly URLs. • Architecture: scalable API layer so we can extend the same business logic to native iOS and Android apps in Phase 2 without rewrites. Phase 2 (planned after the website goes live) will reuse the backend to deliver companion apps on both platforms, so please keep the codebase modular and well-documented. Deliverables for this engagement 1. Functional web marketplace with user, vendor, and admin portals. 2. Source code, build and deployment scripts, plus a brief technical handover. 3. API documentation that will let us kick-start the mobile apps next. 4. Post-launch support for initial bug-fixes and tuning. If you can demonstrate experience with similar multi-vendor or booking platforms and are comfortable implementing MFA, modern UI frameworks, and REST/GraphQL APIs, I’d love to review your proposal and timeline.
