I developed a design system for mobile applications and websites. This design system is primarily intended for financial products, thanks to industry-specific components such as product cards, charts, and tables. The design system consists of Figma components, documentation, a web implementation in React, and a mobile implementation in React Native.
A scalable design system for fintech products across mobile apps and web interfaces. I designed and built a design system for financial products, covering Figma components, documentation, React implementation, and React Native implementation. The system is focused on complex fintech interfaces: product cards, charts, tables, states, templates, and reusable patterns for both customer-facing and operational products.
Fintech products often need to support dense data, multiple platforms, strict consistency, and fast product iteration. The goal was to create a flexible system that could work across web, iOS, and Android while staying easy to customize for different product teams and brand directions.
I worked on the system end to end: structure, component architecture, Figma Variables, documentation, design guidelines, and implementation logic for web and mobile.
The system is built around atomic design and design tokens. Colors, typography, spacing, radius, and platform-specific values are managed through Figma Variables, making the system easy to adapt without rebuilding components manually.
This approach allows teams to switch between light and dark themes, adjust visual style, and adapt Android layouts to iOS patterns with minimal effort.
Typography is tokenized across platforms. The system uses native system fonts for iOS, Android, and web, helping interfaces feel familiar on each platform while keeping the design language consistent.
Text styles are structured so teams can quickly switch between platform presets and maintain predictable hierarchy across product screens.
The library includes more than 40 basic components with documented states, variants, and interaction patterns.
It also includes more than 20 fintech-specific components designed for financial products, including product cards, charts, tables, data displays, and other interface patterns commonly used in banking, trading, and investment products.
Each component is documented with usage guidelines, states, examples, and implementation notes. Documentation is split into two tracks:
Designer documentation: component behavior, variants, states, layout rules, and usage examples
Developer documentation: implementation guidance, props, states, and reusable patterns
The system also documents common product scenarios such as error states, loading states, empty states, templates, transitions, and animation behavior.
More than 40 components with all states, documentation and animation
More than 20 components with all states, documentation and animation
Components are easily customizable — with just a few clicks and minor code changes, you can adjust the color palette, spacing, border radius, and more.
Reduced time spent recreating common fintech UI patterns
Improved consistency across web, iOS, and Android
Created a shared language between design and engineering
Made theme and platform adaptation faster through tokens and variables
