Mobile Buy-Sell App Development

I’m looking to have a straightforward mobile application that lets me showcase items for sale and makes it easy for shoppers to find exactly what they need.

Core features I need right now
• Product listing dashboard where I can add images, price, and short descriptions.
• Fast, intuitive search and category filtering so users can locate items quickly.
• Built-in user reviews and star ratings on every product page, displayed in real time.

That’s all that has to be operational in the first release—no payment processing or account system is required yet, though I’m happy to leave the code flexible enough to bolt those on later.

Technical notes
I’m comfortable with React Native or Flutter, but I’m open to another modern framework if it reduces build time and keeps the code maintainable. A lightweight back end such as Firebase, Supabase, or a simple REST API with a SQL/NoSQL datastore is fine as long as it scales and lets me export the data.

Deliverables
1. Fully functional Android and iOS builds ready for TestFlight/Google Play internal testing.
2. Complete, well-commented source code and asset files.
3. A concise setup guide covering local build, deployment, and how to add new products or moderate reviews.

If you’ve built catalogue-style apps before, especially with rating systems, I’d love to see a quick link or two. Let’s keep the scope focused, ship an MVP, and iterate from there.
