NatWest

I worked as Lead UI/UX Designer on CurrencyPay, NatWest’s international FX payments platform for business customers. The project focused on transitioning a legacy browser-based tool into a secure, mobile-first native app experience.

Role

Senior UI/UX Designer

Duration

1 year

Impact

Launched iOS & Android app

Pain Point

NatWest’s CurrencyPay was originally a browser-based FX tool that business customers found difficult to use on the move. The experience relied on outdated hard token authentication, creating friction during onboarding and failing to meet PSD2 compliance requirements, while complex international payment flows were hard to understand on mobile.

Solution

As Lead UI/UX Designer, I led the end-to-end design of the native CurrencyPay app, redesigning onboarding, authentication and core FX payment journeys. I replaced hard token login with a secure, PSD2-compliant soft token flow, and worked iteratively through prototyping and usability testing to simplify complex payment tasks.

Alongside this, I created a scalable mobile design system and component library to support future payment features and ensure consistency across platforms.

Outcome

The app launched successfully on iOS and Android, delivering a compliant, mobile-first FX experience for business customers. Hard tokens were fully replaced with app-based authentication, significantly reducing friction and improving accessibility.

The design system established a foundation for ongoing product expansion and future payment functionality.
