F-Online is the largest e-learning platform (30% market share) for the Austrian driving license exam. The platform enables free learning of the theoretical driving license questions. During my studies I supported the, quite old, project with the conception of new ideas, but also with the technical implementation of the new landing page. The landing page is generated statically, based on a custom CMS, to get the fastest possible loading times. A new corporate identity was also designed, which is now gradually being adopted. Furthermore, the conception and implementation of an Instagram profile was taken over.

Design and implementation of a static website for my friends of Peifedeggel. The band, based on palatine cultural, can adapt the content themselves with the help of a custom CMS. Also the yearly design change can be done by the band itself. Thanks to the static generation the website loads very fast and a cost-efficient hosting is possible. The Instagram-like gallery allows visitors a quick overview of the art presented by Peifedeggel.

It is important to investigate effects of different interface designs not only for small sample systems but also for large real-world applications. However, it is not always possible for researchers to get direct access to these applications or relevant user data. Studies investigating possible negative effects such as keeping users occupied longer or making them spent more money might not get the consent of the application’s creator. We present a technical architecture and an open source implementation to conduct comparative studies on external apps by enabling researchers to turn specific interface elements on and off. The current implementation requires that the target app is available as a web app and that the study participants access it through a custom Android app. While the framework is not limited to a certain app, we use Instagram as an example and present results from a proof-of-concept study showcasing the framework.

During the Corona Lockdowns I stumbled across an interesting project called Codeprints. After a short conversation with the founders Matthias Endler and Wolfgang Gassler, I supported the project in various areas. From developing new features in the Shopify frontend, to generating new ideas in general. But also in marketing the project was supported in parts. In the meantime the project was aquired by Dyve.

Social networks like Instagram are omnipresent in today's society. Accordingly, the question arises why apps of these networks are used so intensively and frequently. Thus, the goal of this thesis is to create an infrastructure for the analysis of the influence of design patterns on Instagram. Besides the development of a technical basis, theoretical models are presented. In addition to the design pattern itself, the user and his habits in relation to social networks will be considered. A first study, based on the created infrastructure, shows that even the lack of a few design patterns has a great influence on the usage time. These findings are supported and evaluated by the theoretical analysis. The developed infrastructure is designed in such a way that it can be used for further studies and iteratively developed.
