Top SchoolJozef Reisinger is a Sr. DevSecOps Engineer with 13 years of hands-on experience securing, operating and automating Linux and Kubernetes environments for companies across telco, healthcare, biotech, finance and research. He combines deep operational skills (Ansible, CI/CD, SIEM/WAF) with practical software craftsmanship, writing tools and automation in Go, Bash and Python that have uncovered multiple inadvertent data exposures. Certified CKA, LPIC-2, CISSP and CCNA, he has led teams and projects up to ten engineers while running large-scale logging and security deployments on-prem and in the cloud. Known for pragmatic infrastructure-as-code and measurable risk reduction (e.g., dramatic WAF tuning and Datadog SIEM detections), he brings both audit-minded discipline and developer velocity to security operations. Based in Bratislava, he blends networking roots and a Master’s in international economics with an operator’s instinct for resilient systems.
