@CauaAlves

Hi! A Cashify-style marketplace for used devices is a clean build I can deliver. I'd create a mobile-responsive platform where users list and browse smartphones, laptops and tablets, with a guided price-assessment flow (condition questions → estimated value), secure transaction handling, and user profiles with ratings to build trust between buyers and sellers. I'd build it as a responsive web app (extendable to a native mobile app later from the same core) plus an admin panel to manage listings, categories, pricing rules and disputes. Quick questions: web-only to start or web + mobile app, and should pricing be manual rules or based on a device catalog/API? Share any reference flows and I'll map the structure. Ready to start.
