Engineered the end-to-end UI/UX architecture and visual strategy for Vestio, a Fintech SaaS ecosystem designed to simplify wealth management for digital creators and freelancers. I transformed fragmented, multi-channel income streams into intuitive data visualization frameworks, establishing a component-driven Figma design system featuring auto-layout components, custom chart UI widgets, and a dual-mode engine (Light & Dark) optimized for accessibility and user retention.
