Constraint
Payment and physical handoff cross three participant roles, so every order needs a legible state and a verifiable final transfer.

Prototype / Three-sided provisions marketplace
ChopBox
A marketplace concept connecting provisions, mobile money and delivery-code handoffs.
BUY / PAY / HAND OFF
A local marketplace has to make the handoff as clear as the purchase.
How can buyers, sellers and delivery participants coordinate a provisions order without losing track of payment or handoff?
Timeframe
Pilot MVP prototype
Scope
A three-sided marketplace connecting parents, vendors and schools around provisions delivery.
Tools & format
Marketplace workflow model / Mobile Money payment flow / Delivery verification codes
Key decision
Make the delivery verification code part of the transaction model instead of treating delivery as an external afterthought.
What I built
ChopBox frames the product as a three-sided marketplace. The prototype joins product selection, MoMo payment and delivery-code confirmation into one legible order path.
Current stage
ChopBox remains a prototype. The product logic is defined, while operational validation and a public release remain future work.
Validation
The product logic and pilot-MVP direction are documented; operating validation and a public release are not claimed.
Another month
With another month, I would run the handoff model with one parent, vendor and school cohort before widening the marketplace.
