We are building a custom mobile application ("My App Orders") connected to the API ecosystem to streamline appliance part searches and drop-shipping order placements for Romanian users. We already have a complete developer-facing API integration PDF, workflow diagram, and UI mockups in progress. Your job will be to bring this product to life with polished UX/UI and functional implementation, while ensuring App Store and Play Store compliance for deployment. 1. Frontend Mobile App (Flutter preferred, React Native also accepted) Smooth, intuitive UI (based on mockups we provide – adjustments/improvements welcome) Device-agnostic interface (responsive across smartphones & tablets) Login / Register screen (using PrestaShop’s ps_customer database or external) Appliance search flow: Search by keyword, model, manufacturer (geraetesuche) Display grouped parts by category (geraeteartikelgruppen) List relevant parts (geraeteartikel) Direct article search (artikelsuche) with filter options Display technical data, availability, prices, and pictures Add to cart / basket Checkout flow with: Customer fields validation (phone, zip, country, etc.) Shipping method: GLS only Payment method: Cash on Delivery, Bank Transfer, Netopia Order status viewer GLS tracking via iframe (https://gls-group.eu/RO/ro/urmarire-colet?match=...)
