// full stack automation enthusiast

Hi, I'm Stefan de Jager

With a preference for backend logic, process automation and cloud infrastructure, I love diving into any subject in the digital world and am specialized in Kubernetes.
I focus on end-user expectations, clean code, and making products as fun to build as they are to use.

TLDR

Started in 2018

My hands-on journey with technology began during the winter of 2018 after having worked as IT project manager for 5 years. Every project on this site has been created for self-study goals, not monetized assignments.

Software Engineer

Since 2020 I have been software engineer. Initially got to know Linux through working with the LAMP stack. Later, focus shifted to more cloud based solutions with Go and infrastructure configuration with Terraform/Tofu.

Backend Focus

I have a clear preference for backend logic, process automation, kubernetes, and (cloud) infrastructure. I believe code should be easy to read and solve real problems.

Open Source

Thanks to many open source tools, I invite you to use and copy whatever you find on my github page. Sharing knowledge makes our community stronger.

My Career Path

2015 - 2019

It all started in automation. I worked as a project manager for EDI projects in airfreight logistics. While managing those projects, I realized the technical side of automation was what truly fascinated me.

2019 - 2021

Got the chance to join a small sysops team running bare metal Ubuntu servers. I am very grateful for the CTO who showed me the ropes and introduced me to Linux, programming, and the idea that technology is just a means to an end. I participated in moving everything to the cloud, started with Docker, then Kubernetes, and learned Terraform for GCP.

2021 - 2024

Deep dive into Kubernetes, particularly through Talos Linux. I helped architect a platform where Kubernetes was hosted for other companies. This made me more cloud-agnostic - ArgoCD for CD, OpenBao for secrets, Harbor for registries, and so on.

Present

Currently I work as a Kubernetes engineer, building platforms for companies across multiple cloud providers. I focus on combining Kubernetes' strengths with a few conveniences cloud providers offers.
