Senior🎓
Top SchoolJohannes Lauinger is a Senior IT Security Consultant and team leader based in Tübingen with 11 years of hands-on experience across pentesting, web development, and hardware. He combines a practical engineering background—designing web apps with Django, PHP and Angular and building PCBs and embedded systems—with advanced IT security expertise from an MS in IT Security. At SySS GmbH he progressed from consultant to team lead, while running his own web and software practice that handles bespoke systems and network administration. His university roles show deep operational skills in automated deployments (Kubernetes/Ansible, OpenStack/Puppet) and teaching embedded systems. Colleagues know him for curiosity-driven experimentation—often prototyping hardware-software integrations—and a pragmatic approach to turning security findings into actionable remediation. Fluent in both development and security contexts, he bridges blue-team rigor with red-team thinking to deliver resilient, production-ready systems.
