About

RED TEAMER. PENGUINISTA. SYSTEMS THINKER. 20+ years in Linux and open source. I operate at the intersection of computer science and psychology, targeting not just technical vulnerabilities but the human logic and social dynamics that make systems fail. I bridge deep technical execution with strategic threat intelligence. My work is grounded in real-world adversary behavior, including active monitoring of darknet ecosystems (Tor, I2P), to ensure offensive operations are rooted in reality, not just theoretical checklists. • RED & PURPLE TEAMING: Full-scope operations in public-sector environments. I emulate Advanced Persistent Threat (APT) actors using MITRE ATT&CK, combining technical exploitation with social engineering. • THREAT INTELLIGENCE & INVESTIGATIONS: Technical lead and OSINT specialist on TV documentaries (DR, Nordisk Film). I use phishing and digital footprinting to gather evidence on international crime networks and proactively warn potential victims. • SYSTEMS INNOVATION: Recognized by management for building custom vulnerability scanning services that rivaled commercial enterprise tools. BLOCKCHAIN & EMERGING TECH I specialize in extracting signal from noise, identifying technological shifts before they reach escape velocity and acting on them early. Early Bitcoin adopter (since 2010). My master's thesis, "From Blockchain to Blogchain," analyzed decentralized consensus algorithms and their potential for distributed social networks long before the tech became mainstream. THE MAKER MINDSET I use 3D printing to counter planned obsolescence, building parametric OpenSCAD designs for precise, functional repairs. My work has saved consumers ~$500K. I take systems apart, understand them, and rebuild them so they actually work. This spans everything from Raspberry Pi arcade machines to critical infrastructure. My crime is that of curiosity. Give me a problem. Let me solve it. Ad infinitum.

Tutor @ UCSJ TechLab

Oct 2015Dec 2017 · 2 yrs 2 mos · Campus Roskilde · On-site

  • I assisted teachers with filming/video editing parts of their curriculum in an attempt to digitize education. I also taught 3D modelling/printing on the Ultimaker 2 using everything from TinkerCad to Blender to OpenSCAD. I gave wonderful PowerPoint presentations, believe it or not.
  • My amazing colleague Christian Malik Lynnerup and I created some hype and informed students about the TechLab to get more of them actively using it and our expertise in their projects.
  • I also maintained our 3D printers and have experience with several brands (MakerBot, Up!/Chinese replicas, LulzBot, etc).

Co Manager

Jun 2014Jul 2015 · 1 yr 1 mo · Roskilde Festival

  • Two years in a row I have had the privilege of assisting Riccos Kaffebar with co-managing APPARATET (a cocktail bar) during the festivities. Both times with a great set of colleagues and the somewhat looney setting of Roskilde Festival. The bar is run with lots of improvisation (festival requirement) and some wonderful volunteers. Seeing as I've done insane amounts of volunteering in the past, being in charge of volunteers is somewhat of a full-circle experience.

  • I was recruited to support the secretariat department, where I managed mail, shopping, filing, and ad hoc tasks. Keen to contribute further, I proactively sought additional responsibilities and within a short time, I was assisting IT course presenters.
