Story — How I got here

Fifteen years. Building what's next.

2013

Two Danish Internet Awards for the MSF “Like” campaign.

  1. 2008–2011 · Esbjerg

    Computer science. Three years.

    Business Academy West, now SEA. s-e-a.dk ↗

  2. 2010

    It started with security.

    My first job, while still studying: an internship at a security company, 45 minutes away. I had to buy a car to get there, so it cost more than it paid. Worth every krone for what I learned.

  3. Final project

    Built in Unity3D, while it was brand new.

    My final project, in a young Danish engine that had only just reached Windows and gone free.

  4. Agency

    Full stack, full speed.

    Front to back at a young agency.

  5. Freelance · 5 yrs

    OrbiSCADA. Wind, at scale.

    Drove the SCADA system for wind turbines: from one in Denmark to 1,500+ across Denmark, the UK, the USA and Japan. Along the way, Orbital won Børsen Gazelle’s 2018 manufacturing prize for Central Jutland.

  6. Clovr Labs

    Following the money.

    Crypto forensic analytics: blockchain compliance and risk analysis.

  7. Now

    The workspace of the future.
