I need a unified build: a mobile app that runs smoothly on both iOS and Android and an e-commerce website that shares the same backend. For the app, core functions include secure user login and signup, real-time push notifications, and a streamlined in-app purchase flow. The website must present a modern online store experience with product listings, cart, checkout, and basic content management—all responsive across devices so customers feel the same polish they get inside the app. I’ll supply branding assets and early wireframes; you bring UX refinement, clean code, and an admin panel where I can manage users, products, orders, and analytics in one place. To keep everything in sync, outline the stack you recommend (React Native, Flutter, Swift/Kotlin, Node, Django, Laravel, Firebase, etc.) and how you’ll handle authentication, payment processing, and cloud messaging. Deliverables • iOS and Android builds ready in TestFlight and Google Play Console • Fully responsive e-commerce site deployed to my hosting, connected to the shared database • Source code with setup documentation and a short hand-off call An MVP within 6–8 weeks is ideal, with clear milestones for design, development, testing, and launch.
