Craft Marketplace Website & Android App

I’m building a fully-integrated marketplace that connects craftsmen with customers through both a web portal and an Android application, to be released on Google Play. Everything must share one clean, modern design language so users feel the same polished experience whether they browse on desktop or on their phone.

Core workflow
• Craftsmen create listings from a dedicated seller dashboard.
• Customers browse, place orders, and pay; every transaction is stamped with a unique order number as well as seller and buyer ID references for easy tracking.
• Users can rate each other and leave written reviews once a job is completed.
• A built-in messaging system lets buyers and sellers chat in real time; I need supervisor access to those threads so disputes can be settled swiftly.
• Sellers should be able to upgrade to “Featured” status after paying a service fee—this needs to be configurable from the admin panel so I can adjust pricing or run promotions.

Before any advertisement goes live, the system should prompt the seller to choose a promotion plan (free, standard, or featured) and then apply the correct visibility rules automatically.

Deliverables
1. Responsive website (front end + seller/buyer dashboards + admin panel).
2. Native-like Android app published to Google Play under my account.
3. Source code and deployment documentation.
4. A brief hand-off session so I can manage users, monitor messages, and toggle featured-seller fees without developer help.

Preferred tech stacks are flexible—feel free to suggest Flutter, React Native, Kotlin, Laravel, Node JS, or others you’re confident will scale smoothly—but the final product must be stable, secure, and easy for me to maintain.

If you have launched similar marketplace platforms, especially with in-app messaging and review systems, I’d love to see your work and discuss timelines.
