Experience

Software Engineer

Tern Systems ehf • 201, Kópavogur | December 2021 - Present

As part of a two-person development team, I worked on the TAMS AMHS and ROFDS projects, modernizing legacy C++/Qt applications by migrating them from 32-bit RedHat 6 to 64-bit CentOS 8.5 and Rocky Linux 8.10. We designed a new installation process and built custom Linux distributions, automating OS and software deployment. To streamline development, we integrated the projects into Jenkins for automated builds and releases. Working closely with a product manager and later testers, I gained expertise in Linux, C++, CMake, Networking, Jenkins, Docker, VMWare, VirtualBox, Bash scripting, Ansible, and AsciiDoc. Additionally, I developed and released the Sheller VS Code extension to simplify Bash scripting, available on the Studio Marketplace https://marketplace.visualstudio.com/items?itemName=guttih.sheller
