I really love building things for the internet together with other people. I enjoy mob programming, pair programming and doing things solo. Since 2004, I’ve held various roles focused on system administration, operations and development.

My main employer has been:

  1. Code Labs AB (2022-2024)
  2. Sveriges Television (2017-2022)
  3. Kundo (2017)
  4. Swedish Security Service (2012-2017)
  5. Swedish Armed Forces (2004-2012)

By working with the aforementioned agencies and companies, I have acquired a deep knowledge of what's required to run and operate complex software systems within organizations which have extremely high security standards.

I have continuously kept my skills up to date driven largely by a strong personal interest in programming, systems networking and security, working with amazing people and by attending security-focused courses and conferences.

I love building things together with other people and seeing the finished product. I enjoy mob programming, pair programming and doing things solo.

  9. Swedish Armed Forces and Swedish Defence Materiel Administration Consultant

    Stockholm - Server Technician

    September 2007 - December 2011

    In September of 2007, I started as a full-time consultant at the Swedish Defence Materiel Administration (FMV) in Stockholm on project Fenix. Fenix is a web based aviation maintenance system for the Swedish Air-Force.

    I was part of the early team that took the Fenix platform into production, and worked on migrating the existing JAS–39 Gripen (Swedish fighter jet) fleet from its previous archaic systems onto the new Fenix aviation maintenance platform. Since the project went live, the Swedish Air-Force has continued to migrate several other aircraft types onto the new Fenix platform.

    I started as a systems administrator for the development and testing infrastructure, which consisted mainly of Microsoft Windows and Sun Solaris servers. Part of my responsibility was also to work with the development team on quality assurance and testing of new releases before they went into production.

    As the project grew in size, the demand for more rapid deployment and testing increased. I was tasked with designing and configuring a new development platform, which was based on technology from Dell, EMC and VMWare.

    In 2010, I switched roles and began working as part of the development team at FMV. As part of the export of the JAS–39 Gripen to the Royal Thai Air-force, I worked on creating product specifications and test cases for any new functionality that was required.

  10. Ström2 Consultant Group Consultant

    Stockholm - Server Technician

    In 2007, I started at Ström2 Consultant Group. Along with the change of employment from IT-Resurs to Ström2, I also started working at the Headquarters of the Swedish Armed Forces in Stockholm.

    In addition to being a full-time consultant for the Swedish Armed Forces, I worked with the in-house IT Infrastructure at Ström2. As the IT Manager at Ström2 I was responsible for keeping the main office systems up and running.

    To make the server environment more manageable I rebuilt it and virtualized it using technology from VMware, Microsoft and Linux (mostly Debian).

  11. IT-Resurs/Swedish Armed Forces Consultant

    Uppsala - Support Technician

    2005 - 2007

    In October 2005, I started as a IT-Support Technician at the Military Garrison in Uppsala. I was part of the team that supported the Swedish Operational Command, which was stationed in Uppsala at the time.

    Although I mainly worked with the unclassified infrastructure, I went through additional training on handling classified material and equipment.

  12. Swedish Armed Forces

    Stockholm - Conscript

    2004 - 2005

    In July 2004, I began my basic military training at the Karlskrona Naval Base. After the 8 weeks of basic training and an additional leadership training course we moved from Karlskrona to the Swedish Military Headquarters in Stockholm.

    The daily activities consisted of user support, logistics, user training, server and network management, IT security and a final individual project. We worked side by side with both employees of the Armed Forces and Consultants. We had the daily support responsibility for one of the floors of the Headquarters in Stockholm.

    My final project consisted of the development of a Light Touch Deployment Server, used for remote installation of Microsoft Windows XP clients. The server was later taken into production and used on the Internet LAN at the Operational Command in Uppsala. I left the Swedish Armed Forces after my 15 months conscription was over as a Sergeant, with the final mark of 10–8–9 out of 10–9–9.
