I’m building a single-platform Android application that lets customers book on-demand salon and beauty services to their home. The workflow is straightforward: users register with their phone number, browse a catalogue of services and packages, view stylist profiles, choose a time slot, and pay securely in-app. Core features I need developed: • Real-time appointment booking with stylist calendar management • Rich service & package listings that support images, descriptions, and variable pricing • Individual service-provider profile pages (ratings, portfolio photos, distance, specialties) • Secure payment processing (major cards, wallets, or UPI) with success / failure callbacks • Loyalty or rewards program logic so clients earn points for each completed service and coins reward program. Please include a lightweight admin or provider dashboard—web-based is fine—to approve stylist sign-ups, manage listings, view bookings, and trigger reward redemptions. Clean, modern UI built to current Android guidelines is important, and well-structured code that I can extend later is essential. On delivery I’ll review: 1. Source code & build instructions 2. Working APK demonstrating every feature above 3. Simple database schema or API documentation 4. Short video or walkthrough proving each user flow functions end-to-end Tech to be used: Front end: Flutter Backend: Node.js with Express.js Database: PostgreSQL Cloud: AWS/GCP with Firebase (for scalability and notifications) If you have prior experience with booking or on-demand service apps and can hit these acceptance points, let’s discuss timelines and milestones.
