The Problem

Event organizers in Jos faced challenges finding reliable vendors and making secure payments. Vendors struggled with payment collection and booking management. There was no trusted intermediary to protect both parties.

The Solution

Created a vendor marketplace with verified profiles, escrow-protected bookings, milestone-based payment releases, and integrated Paystack processing for seamless transactions.

Challenges

1Building trust between organizers and vendors in a new marketplace
2Implementing milestone-based escrow releases that satisfy both parties
3Handling payment disputes with fair resolution mechanisms

Engineering Trade-offs

1Chose ISR over full static generation for vendor profiles — pages stay fresh as vendors update listings, at the cost of occasionally serving a slightly stale page between revalidations
2Sequenced reviews before escrow rather than shipping both together — let trust signals accumulate before real money moved through the platform, delaying the more complex escrow feature
3Chose manual admin dispute resolution over automated rules at launch — the right call during a low-volume launch phase, at the cost of not scaling past a small support team without further investment
