UniMarket
Live
UniMarket is a live multi-university marketplace connecting students across Nigerian campuses to buy, sell, and trade safely. As lead engineer, I built escrow payments so funds only release after a confirmed handoff, a verified-seller system, and the AI layer behind search ranking and content moderation — including a rule-based moderation check you can try below, a simplified version of the real system in production.
Live demo
Try it yourself: this is a simplified version of the real moderation system I built for UniMarket.
Type a fake listing, run it through real rule-based logic (not a mockup), and toggle between the version I shipped before the fix and the version I shipped after.
Awaiting input. Type a listing above and run a check.
Worked example (interactive on screen)
“Textbooks for sale” — Intro to Economics and Calculus 2 textbooks, used but in fair condition. $15 each or $25 for both. Call only 08012345678.
Something in the text looked a little risky at first glance, but the listing itself was well-written and detailed, so the system let it through instead of holding it. That's the fix, working.
