I will develop a mobile application for group buying under a turnkey agreement

I make mobile applications specifically for group buying — when one organizer gathers a group for a wholesale goods batch, participants join and contribute their share, and the application monitors whether the necessary sum has been collected, and divides the delivery cost among everyone participating. This is not a universal bill splitter — the logic is built around group buying mechanics: minimum batch size from the supplier, timer until collection closes, automatic recalculation of each person's delivery share when a new participant joins.

Over several projects I have built a working scheme: the organizer creates a group buy with product description, required quantity, price thresholds and deadline; participants join in a couple of taps, reserve their share and pay through the built-in payment gateway or confirm payment manually; the application in real time shows the progress of sum collection and recalculates each person's delivery share if someone joins or leaves. I separately create notifications about approaching deadline, a refund mechanism if the collection doesn't reach the goal, and an organizer panel for managing multiple group buys simultaneously.

What is included in development:
— mobile application for iOS and Android
— server part with payment and delivery share calculation
— organizer panel for managing collections
— push notifications and collection statistics

I work with both ready-made design and from scratch, provide support during testing and launch.
