Hey 👋🏼 I'm Niklas — a software engineer from Cologne.

My name is Niklas Metje, from Cologne, Germany and this is my website about topics I find interesting and a place where I document my learnings. I try to write in such a way that it’s easy to understand even if one does not have the same understanding of the topic yet.

In 2015 I started an apprenticeship as an IT-specialist (system integration) with the University of Cologne where I worked at the universities’ administration and the regional computing centre (RRZK). After I finished my apprenticeship in 2018, I finished studying Business Information Systems at the University of Cologne in 2021. In addition to my studies I worked as a working student in software development at cologic GmbH & Co. KG. My main focus there was on web and cross-platform app development with Ionic and Angular. Due to my education I am also very interested in automation and service provision with e.g. Docker. After finishing my studies I started working at FOND OF GmbH as a DevOps Engineer.

Since September 2022 I am a maintainer of the CNCF's OpenGitOps project. With two of my friends I started the local meetup series called entbit. cologne where we want to bring together DevOps, Site Reliability Engineering and everyone interested in cloud topics in general.

In early 2024 I started working on Everything I know about Deno, a Deno course for beginners and advanced users. I want to show how to get started with Deno, use the tooling, create applications and deploy them.

After more than 4 years at FOND OF I had the chance to build a whole application plus infrastructure from scratch. I joined Hylaw in February 2026 as a software engineer. Being close to the insurance industry means working with regulation (GDRP, DORA, etc.). Therefore we try to build as eu-sovereign as possible. That means hosting, third-party tools from real EU companies.
