DenizPay App

Extending an Existing Mobile Experience

DenizPay, formerly fastPay, is a digital payment platform built around everyday financial transactions. My work focused on designing new screens and adapting existing experiences as product requirements evolved, rather than redesigning the application from the ground up.

The main challenge was introducing new functionality while keeping each addition consistent with the product’s existing structure, interaction patterns, and visual language.

Translating Product Requirements into Interface Solutions

As a UI Designer, I worked on selected screens and flows within the existing mobile product. For each requirement, I reviewed the surrounding experience and defined how the new interface should fit into the broader journey.

Where needed, I worked through user flows and wireframes before moving into final interface design. I focused on content hierarchy, transaction steps, system states, and feedback to make financial actions easier to follow while maintaining consistency across the application.

Maintaining Consistency as the Product Evolved

Rather than treating each requirement as an isolated screen, I designed new interfaces around the patterns already established within the product and extended those patterns when necessary.

This approach allowed new screens and functionality to become part of the existing experience without introducing unnecessary visual or interaction inconsistencies, creating a more coherent foundation as the product continued to evolve.
