Profile

About

As Information Security Officer and Head of Internal IT at innobis AG, I set the strategic and organisational framework for the company's information security and internal IT. I lead the internal IT team, steer IT and security projects, and make sure that security, operations and business requirements fit together. Our information security management is guided in part by ISO 27001 and BSI IT-Grundschutz.

In parallel, I remain active in SAP projects for financial institutions as senior consultant and service manager – including responsibility for sub-projects in an SAP banking merger. I joined innobis in 2017 as an SAP development consultant.

With more than 20 years in enterprise IT, I know the field from the ground up: I started with an apprenticeship as an IT systems electronics technician, building networks and installing and commissioning control systems. Before innobis, I spent over a decade at W. Brandenburg GmbH & Co. oHG, progressing to head of IT. My interest in technology began before the internet became part of everyday life, in the days of dial-up modems – and the curiosity that started then still drives my work today.

My focus is on IT that is secure, reliable and aligned with business goals – with clear responsibilities, sound processes and a team that can deliver. As a Linux and open-source enthusiast, I also run my own lab environment as a safe space to try out new technologies and methods, and bring what I learn there into strategic decisions and our day-to-day work.
