My contribution

ZEN.com is a fintech app that simplifies payments and financial services for people and businesses. I worked across its mobile experience, helping shape ideas into user-centred designs and supporting them through delivery.

My contribution

I was responsible for UX design, UI design, and ideation. I partnered with business and analytics teams to understand user needs, create user-centred solutions, and work with developers to bring them to life.

The team

I was part of an eight-person design team at a startup of more than 100 people. The team included product designers, analysts, UX researchers, and brand designers, working closely with product teams across mobile, web, and back-office tools.

Process

From idea to handoff

I started from the ideation phase, collaborating with designers, product managers, and stakeholders to explore the problem space and align on a solution. I then prepared detailed designs, user flows, and edge cases to support implementation and later refinement.

Implementation and iteration

During development, I tested early builds, checked edge cases, and worked with engineers to make sure the final result matched the design. After release, I used product data and usability testing to understand behaviour and improve the experience.

Outcome

ZEN launched with major promotions in Poland and other markets, attracting tens of thousands of users on its first day. Working on the launch was a defining learning experience, and the product has since grown into one of Poland's leading fintech companies.
