Hi, I'm Thomas
I can be hired for all kinds of things that have to do with the internet (or as we call it here in Germany: "Das Internetz").

Kubernetes / Container Orchestration
I've been knee-deep in Kubernetes and its variations like k3s since 2017, setting up apps everywhere from big cloud services to the little guys on the edge. This dive into container orchestration is my secret sauce for building tough hybrid clouds that keep services running smooth.
Cloud Native
I'm well-versed in whipping up scalable systems with Docker and LXC/LXD, and I'm handy with tools like Earthly and Helm. My skills with KubeVirt and various CNIs, plus Kubernetes operators, mean I'm all about efficient, service-driven cloud tech.
Infrastructure
I'm big on automation, using Terraform and GitOps to make infrastructure setup and management slick and efficient. My work automates not just deployments but the whole cloud management game. ^
DevOps and Continuous Integration/Delivery
Automation is key in my work, making delivery systems super efficient. I use GitLab, Packer, and more to build solid CI/CD pipelines, whip up VM images, and keep testing sleek. Handling k3s clusters and OpenStack instances shows my all-in DevOps approach.
Development
I kicked off with Java and Kotlin, then got hooked on Golang for cloud magic. On the frontend, I’ve mastered Vue, Angular, React, and played with Next.js and Astro.js, blending tech expertise with a creative touch across the whole dev lifecycle.Now match your favorite buzzword tag below
