Role

Co-Founder & Product Designer

Overview

"I designed the full product across web and mobile. Now a non-executive shareholder."

Egyptian & African professionals and consumers faced severe financial barriers when participating in the global digital economy due to restrictive local banking infrastructure and high-friction cross-border payment gateways. Card-Y was engineered to dismantle these obstacles by allowing users as a first step to fund accounts locally and spend globally.

As co-founder, I owned product design end to end. I designed 100% of the digital product experience across web and mobile while directly leading a 6-person cross-functional engineering team to build, scale, and launch the platform from scratch.

Measurable Impact & Scale

  • $1M+ Monthly Volume: Scaled the platform to process over $1,000,000 in monthly international transaction volume across 40,000+ active users.

  • 75% Faster Onboarding: Streamlined the identity verification architecture, compressing activation time from 2 hours to just 30 minutes and boosting completion rates by 64%.

  • Full Mobile Transformation: Successfully directed the product evolution from a web-only dashboard into a secure, native biometric mobile fintech application.

Core Systems Architected

  • Multi-Layer Ledger UX: Designed a scalable information architecture that cleanly separated core user identities, dedicated global USD/EUR bank accounts, and segregated virtual/physical spending cards ($100 launch tier).

  • Frictionless KYC & AML Engine: Architected a progressive, biometric onboarding funnel that dynamically handled document verification and compliance screening, mapping out intuitive recovery paths for flagged or pending states.

  • Cross-Border Liquidity & Wallets: Formulated workflows for local currency top-ups and instant balance transfers, laying the technical UX groundwork for Visa/Mastercard processing and Apple/Google Pay tokenization.
