Summary
👤
Senior🎓
Top SchoolDavid Bjørnsten-lindhard is a Security Architect in Copenhagen with over a decade of professional experience and a hands-on career in networking, system administration and programming stretching back to 1996. He blends red‑teaming, pen‑testing, threat hunting and forensic analysis with practical hosting and operations expertise—managing web, mail, SAN, backup and colocation environments as second nature. Deep mainframe knowledge (z/OS, MVS, TSO/E) and legacy languages like COBOL, JCL and assembler complement his Linux/Unix and network security specialisms. At Nuuday he moved from IT developer to Security Architect, applying both offensive security skills and infrastructure stewardship to improve resilience at scale. An entrepreneur who has founded and run hosting and services companies, he brings operator instincts to architecture and incident response. Notably, his toolkit ranges from Wireshark-driven packet hunts to writing tooling in C, Perl and Bash, reflecting a practitioner who prefers evidence-based, low-level investigation.
