I’m expanding my retail operation into a fully digital storefront and need an experienced developer who can deliver both a polished website and companion mobile apps. The project covers three platforms—responsive web (desktop + mobile), native iOS, and Android—and must feel seamless across the board. Core functionality I must see on day one: • Product catalog with flexible categories and search • Smooth shopping cart workflow • Secure payment gateway integration (major cards and wallet options) Design and performance count; I’m after fast load times, clean UI/UX, and code that scales as inventory grows. If you have a preferred stack or framework, let me know why it fits—whether that’s React + Node, Laravel, Flutter, or another modern approach—as long as it keeps maintenance straightforward. Please outline: • Your proposed tech stack and architecture • Example e-commerce projects you personally built • A realistic timeline broken into milestones (web first is fine, but all three platforms are required) I’m ready to move quickly once we agree on scope, so clear communication and the ability to demo progress regularly will be essential.
