A production-ready Figma design system built specifically for Islamic finance apps — not a generic UI kit. 690+ screens (173 flows × Light/Dark × Arabic RTL/English LTR), 199 fully-variant components, 448 color variables, and real financial logic baked into every flow: Zakat calculation with Hawl/Nisab tracking, circular debt settlement, sub-account budgeting, and an immutable audit trail. Built solo over 7 months. Everything is wired — interactive prototype included, not just static screens.
