Lead Researcher IoT Security
University of Paderborn
(Internet und Informationstechnologie)
Technical lead in a research project responsible for the automation of the initial distribution as well as the lifecycle of x509 certificates in (I)IoT use cases. Integrated various IoT platforms with different Key Management Systems while the devices’ identities were managed along the supply chain. The overall system security relies on a hardware bounded client identity which is saved in a HSM (TPM/ATECC 608) on the device. Automated setup of a 3 tier PKI (incl. offline root) for OPC UA and MQTT use cases. Management of a 7 member software developer team. Development and documentation of technical requirements. Master’s thesis Mentoring.

Backend Developer, Software Engineer, System Engineer, System Administrator
maxcluster GmbH
(Internet und Informationstechnologie)
My work experience contains the automation of installing Mail- and DNS-Server and Hosts for container virtualization. I introduced an infrastructure wide host and employee authentication service via Kerberos. Because of the small amount of employees, I got close insights in team government and team management while the company was growing.
