Merchant Portal | First Data


About: Merchant Portal version before rebranding in the 2021 as First Data was acquired by Fiserv and a name disappeared from the market.

My role: 50% team management, 50% hands on design (UX, UI, User research).

Responsive and PWA application

Merchant Portal is a responsive application (RWD) with every screen designed to be used in 3 major breakpoints. Most features are accessible regardless of the user device. It is also created as a PWA application (Progressive Web App). Currently one PWA version is deployed to the Google Play Store (OnePortal24 for Poland).

Financial application for merchants

Merchant Portal is a financial application. It's main feature are Financial views - tables with pre-authorisations, authorisations, transactions, funding etc. Table is a Design System component. It is versatile so when creating a new view that require a table grid, front-end developers don't need to ask for a new design - they are implementing based on the component description.
