BNPL fintech used by millions across MENA. App Store

Designed the iOS design system from zero — architecture, components, naming — with every component built cross-stack for both UIKit and SwiftUI behind one configuration layer.
Automated the Figma → code pipeline for colors, icons and typography, including an internal Figma plugin that emits UIKit and SwiftUI code.
Built a new navigation layer that removed most of the UIKit–SwiftUI bridging friction, plus internal frameworks (VDPin, VDLayout, VDChain) that the team adopted for everyday UI work.
Owned platform projects end to end — proposal, architecture, rollout, adoption — alongside Kotlin Multiplatform integration, CI pipelines, a runtime UI inspector, and DocC/Docsify documentation.
