Hallengreen Hansen

I am a DevOps Engineer focused on keeping platforms running, reliable, and easy for developers to ship to. My day-to-day is Kubernetes, CI/CD pipelines, containers, and infrastructure as code — along with the on-the-ground work of supporting developers when something breaks or needs to move faster. I am a Certified Kubernetes Administrator (CKA) and a Microsoft Certified: Azure Administrator Associate (AZ-104).

On the operations side I work with Kubernetes, Docker, Terraform, GitHub Actions, and Azure, plus the usual glue around them — ingress and routing, secrets, authentication with Authentik, monitoring, and troubleshooting whatever is actually going wrong at 4pm on a Friday. I like automating the boring parts and making the path from commit to production boring in a good way.

On the development side, C# is the language I know well and reach for by default. I have also worked with Java, Kotlin, Swift, JavaScript, TypeScript, React, and Go across studies and projects, but those are not part of my daily work — I can read and get around in them rather than claim depth. Same goes for databases: I have built with MySQL, PostgreSQL, MongoDB, and Neo4j, mostly in a project context.

I graduated in January 2026 with a Bachelor's degree in Software Development from Københavns Erhvervsakademi (KEA), and in 2024 with an Academy Profession degree in Computer Science. During my studies, I completed an exchange semester at HOGENT University of Applied Sciences and Arts in Belgium. Before moving into tech I spent years in ship spares logistics, which is where I picked up the habit of treating uptime and deadlines as non-negotiable.

I have experience working on real-world projects at companies like Swift Marine and Tech Chapter. Read more about these projects below.

When I'm not coding or working, I'm usually lifting weights at the gym, climbing on boulders, playing with home automations, gaming, or kicking back on the couch watching football, movies or series.
