Business Informatics · Product Management · Fraud & Verification

Hi, I’m Denizcan Güney.

Business Informatics student at HWR Berlin. I work at the intersection of product, data and IT-driven processes.

About me

I am a Business Informatics student at the Berlin School of Economics and Law (HWR Berlin) and work in parallel as a working student in product management at Jelbi. My focus there is on verification management, fraud monitoring, fraud prevention and data-driven product improvements.

Before transferring to HWR Berlin, I studied Business Informatics at Technische Universität Berlin and completed a semester of Computer Science at Freie Universität Berlin. This gave me a strong background in the automation of business processes and the technical foundations of digital products.

I am especially interested in the interface between technology, product and user experience – particularly in areas where security, verification and clean data processes are critical.
