I’m planning to launch a mobile marketplace where real-time auctions are streamed directly to viewers—think Tilt, but tailored to my brand. I need a full-featured build for both iOS and Android that lets users register, create rich profiles, go live to sell items, and bid in real time. Core must-haves • Robust user registration and profile management that handles Buyers, Sellers, and Administrators out of the box. • Seamless live-streaming integration so sellers can broadcast without third-party work-arounds. • A solid auction management system that schedules, lists, and closes sales with automatic bid increments and clear winner notifications. For deliverables, I’m expecting production-ready apps, clean modular code, and a lightweight admin panel so my team can oversee users, streams, and auctions without touching the backend. A quick outline of your preferred tech stack, any relevant portfolio links, and a high-level timeline will help us kick things off smoothly.
