Payment platform with 30% fraud reduction at $10M+ monthly volume
Embedded on a live Buy-Now-Pay-Later platform in the UAE, I shipped the payment gateway, the fraud-scoring layer, and the identity verification flow on real-money production. 99.99% uptime, 30% fraud reduction, 10,000+ daily users.
Outcomes
The problem
The platform runs Buy-Now-Pay-Later checkout for over 10,000 shoppers a day, and every transaction moves real money. It needed a payment gateway with bank-grade uptime, a fraud posture aggressive enough for a regional fraud landscape that was maturing fast, and customer-facing surfaces that met UAE accessibility expectations in Arabic and English.
Constraints
- 99.99% uptime SLA on the payment surface
- WCAG 2.1 accessibility, RTL Arabic + LTR English
- PCI-aligned posture for cardholder data flow
- Real-money production traffic from day one
What I built
- 01Led the payment gateway integration end to end, including failure modes and retry logic
- 02Wired a third-party fraud-scoring SDK into the transaction layer with a feedback loop into the rules surface
- 03Built Next.js platforms for purchase reporting and for the facial-recognition identity check
- 04Implemented WCAG 2.1 localization across the customer-facing surfaces
- 05Operated production payment systems through real-money rollouts and incident response
