Zoltán Hosszú

I’m a designer and creator. I love building digital experiences that solve real problems.

Currently leading the design efforts of Deutsche Telekom's Design Hub where I spend most of my time working on international projects designing UX & UI. It's super exciting to be able to work on products used by millions of people all over Europe and to do this with a talented and friendly team.

In my spare time I build apps in Swift for Mac and iOS. Teaching has also become a part of my life and I’m very grateful for that. Giving back to the community is amazing.

Our team released the new Telekom app

2020 April

When I joined Deutsche Telekom in 2018 our team, Design Hub was mostly doing design localization of German products for the local markets around the EU. But in early 2019 we got the chance to become the lead design team for the redesign of the most important European product for Telekom: the self-care mobile application. It was already being used by over 5 million users monthly so it was quite an exciting challenge. Together with the awesome management and development teams we released the app to 9 countries. Read more about the process in this interview in Hungarian, or the story from the Product Owner's perspective.

I build my own IoT hardware now!

2019 December

As one of my main goals for 2019 I decided to try to make my home smarter. At first I just wanted to create a something simple. The fascination grew and grew and so did the possibilities I realized a home had. I learn a lot each time I create something. And because I've never had any experience with electronics before I struggle a lot. But today I can manage my alarm system, open and close the garage door, control many lights, set the heating or cooling and many more fun things, all integrated through Apple's HomeKit. I love doing this and it's a great and mostly cheap hobby.

Started teaching at Hungarian University of Fine Arts

2019 March

The Hungarian University of Fine Arts is one of the most prestigious art schools of Hungary. UI Academy is a special 3 month course run by the university and organized by three amazing people. When they reached out to me to teach UI design basics and UI animation I knew I would love it. I wasn't wrong :) And at the end they even invited me to judge the final work and performance by the students, which was a total blast! It's been an honor to continue teaching each semester ever since.

Founded the Arkon Design team

2013 February

The company structure at Arkon for people working in a design-related field was kind of a headache, we had no clear company hierarchy, so with the help of the management and HR, Balázs Dömsödi and we started the self-managed Design team at Arkon.

Released GAget for Mac OS X

2011 August

The Dashboard of OS X doesn't get much love from Apple and developers, but I believe it could be really useful if there were great widgets for it. That's why I developed GAget for Mac OS X, a Google Analytics widget for quick and easy access to the most important data of your GA account.


Redesigned my portfolio

2011 February

The skeuomorphism was really booming in 2011 so I was not going to be the one left out. A digitally drawn room, bookshelf on the wall, a drawing of myself, wooden buttons and flickering lamp lights were all essential parts of this fully skeuomorphic design. :)
