Project description:
"I have thirty days to launch a complete mobile marketplace ecosystem and need a single team that can move fast and deliver four tightly-integrated apps for both iOS and Android.

Deliverables
• Customer App – browsing and ordering of products or services, real-time order status, in-app chat for customer support, plus a secure payment gateway.
• Vendor App – add/edit listings, view and act on orders, access analytics and reports, and reach our support channel when needed.
• Delivery Partner App – accept or decline assigned jobs and update delivery progress (we will fine-tune exact screens together).
• Admin Console/App – oversee customers, vendors, deliveries, payments, inventory, and push notifications from a single dashboard.

What I need from you
• Cross-platform build (iOS + Android) using a modern stack such as Flutter, React Native, or a comparable framework that can hit our four-week deadline.
• Robust, well-documented REST or GraphQL API, real-time notifications (Firebase, OneSignal, or similar), secure authentication, and scalable database design.
• End-to-end ownership: UI/UX, coding, QA, test flight/beta builds, and final submission to both stores.
• Weekly demos so we can iterate quickly and keep the timeline on track; source code handed over at every milestone.

Acceptance Criteria
1. All four apps pass functional testing for the features outlined above on current iOS and Android versions.
2. Store submissions approved or ready for release with no critical issues.
3. Codebase and documentation delivered, enabling our in-house team to maintain and extend the product.

If your team has a proven track record delivering multi-role marketplace applications at this pace, let’s lock in the schedule and get started right away." (client-provided description)
