I'm looking for an experienced IOS app developer to create an e-commerce app. The app should include: Main Functionalities (MVP) The Minimum Viable Product should be ruthlessly focused on the "Scan → Done" workflow. Avoid feature creep at all costs. 1. One-Tap Scanning • Functionality: The app opens directly to the camera. The user takes a picture of the receipt. That's it. No extra buttons or menus. • Under the Hood: The app automatically detects the edges of the receipt, crops it, enhances the image for readability, and uploads it. • Selling Point: "The fastest way to capture a receipt." 2. AI-Powered Data Extraction • Functionality: Once the image is captured, our AI backend automatically and instantly extracts the key information. • Data Points (MVP): • Vendor Name • Date • Total Amount • Tax Amount • Category (e.g., "Office Supplies," "Meals," "Software") - AI will suggest a category. • Selling Point: "Let AI do the typing. Never manually enter a receipt again." 3. Real-Time Google Sheets Integration • Functionality: The extracted data, along with a link to the scanned receipt image, is instantly added as a new row to a user-designated Google Sheet. • Setup: During onboarding, the user authenticates their Google account and either selects an existing spreadsheet or lets the app create a new one for them with pre-defined columns. • Selling Point: "Your expenses, in your spreadsheet, in real-time. No more exporting CSVs." 4. Simple Onboarding • Functionality: A 3-step onboarding process: 1. Welcome screen explaining the "Scan → Done" value. 2. Connect Google Account. 3. Select or create your destination Google Sheet. 4. Subscription screen (onboarding paywall). • Selling Point: "Set up in 2 minutes, save hours every month." - Email/Password user authentication - In-app purchase functionality Ideal Skills and Experience: - Proven IOS app development experience, especially in the e-commerce sector - Strong knowledge in implementing secure email/password authentication - Expertise in integrating in-app purchases - Familiarity with app store submission and compliance Please provide samples of previous similar work.
