About

I am an experienced technology leader with a passion for innovation, problem-solving and pragmatism.
My expertise spans aligning technology with business goals, scaling digital platforms, agile development, full-stack development, leading large cross-functional teams and building a strong engineering culture.

At 18, I started my own web development company, setting the foundation for my career in IT. While studying Computer Science at the University of Konstanz I gained hands-on experience as a working student at OpenText. My professional career started at CHECK24 advancing from full-stack developer to a Head of Department where I managed multiple, cross-functional IT teams. Then I joined INFITECH GmbH as the CTO, driving the digital transformation, optimizing development processes, and fostering innovation across all portfolio companies.

Meinungsanalyse in Textdaten: Chancen der interaktiven Steuerung des Analyseprozesses
Published by Akademikerverlag

Opinions affect us in our day-to-day decisions. In the past, purchase decisions were discussed with family members whereas today we can also utilize the internet where users are able to reveal their experiences within reviews. Based on these reviews buyers are able to identify strengths and weaknesses of the respective product features. Caused by the large amount of data, techniques of computational linguistics and computer science shall help - however, with limited success so far. Often, information can only be resolved with the user's world knowledge. This book describes the chances and the development of an interactive steering process which embodies a connection between man and machine in order to improve the analysis process on opinionated texts.

Entwicklung eines Modells für die Repräsentation tabellenförmiger Daten aus Dokumenten
Published by Akademikerverlag

Tables can be found in almost every medium. They provide the reader with structured data which would be by far less obvious from text only. Whereas humans do not have great difficulties with recognizing structured data in table forms, automatic computer processes have to collect these information arduously from various sources to understand the data structure. Both the amount of different document types and the different types of table layouts complicate the process of automatic table extraction. An exchange of tabular structures between the most common document types is not supported. This book describes the development of a model that represents tabular data across different document types.
