Role

UX/UI Designer

Background

Below, you will find some of the other work that I did while working for T-Mobile PL. Although it was not part of the add-ons case study, I believe it is important to showcase what I have been working on.

Design Systems

In addition to my other responsibilities, I also maintained our small design system. I ensured that:

All components were up-to-date, properly organised, and easily accessible for our developers, product owners, researchers, and anyone else who needed them

I regularly updated components in Figma whenever new updates were available, such as auto-layout and variant components

I developed components that helped maintain a consistent look and feel for modals and cards across all viewports

Mockups for user trials

During my time at TMPL, we conducted two user tests with actual customers using Figma prototypes since our product was not yet live or stable. We interviewed a total of 20 people for two different parts of the website we were working on at the time. During that process I learnt:

How to make prototypes specifically for user research

How to write scenarios for user interviews

How to make quality assurance for prototypes and best practices to check for the errors

How to collaborate with other designers on prototypes
