OTP Bank is a leading financial institution offering modern banking solutions across digital and physical channels, with a focus on secure, accessible, and user-friendly financial experiences.

Project overview

For OTP Bank, the focus was not on redesigning the interface, but on strengthening the product’s design system infrastructure. The aim was to improve scalability, consistency, and accessibility by developing a clear token structure and supporting the implementation process across digital touchpoints.

My Role

• Design System

• Token architecture

• Primitive & semantic token structure

• Token naming & organization

• Scalable design system foundation

Problem

• Inconsistent token usage

• Lack of clear token hierarchy

• Limited scalability

• Difficult design–development handoff

• Need for a structured token foundation

Project process

We worked on organizing the design system foundation through token structure, semantic naming, and reusable design logic. Alongside this, we focused on accessibility requirements to help ensure a more inclusive user experience. Throughout the process, we stayed in close communication with the development team, providing guidance, clarifications, and design system support during implementation.

Final result

The project resulted in a more structured and developer-friendly design system foundation for OTP Bank. With improved token organization and accessibility support, the product gained a stronger infrastructure that could be maintained, scaled, and implemented more consistently across future digital experiences.
