2012 - 2019

Unmuted started out as a blog and web hosting company. With this expertise, we changed our focus to radio streaming services. With only a small investment, we became one of the market leaders in our field. Today we strongly invest in our own platform including the development of our own streaming and automation software

I started out managing the server infrastructure of the software we used. I also developed the mobile applications we offer to our clients. I also provided support to clients via support tickets. Later, my development role became more prominent as there was demand for special software - which led to developing our own control panel, streaming server, station automation software and even server orchestration for these new services.

Intern SRE

March 2018 - June 2018

For my education I did an internship at the platform team of GoCardless in London. Here I worked on te migration from existing containerized systems running on bare metal to Kubernetes running on Google Cloud Platform. This involved developing developer tooling as well as moving production applications.

Sr. DevOps Engineer

September 2018 - November 2019

As DevOps engineer at source{d} I designed and managed several Kubernetes clusters as well as other services. These consisted of a mix of bare metal and cloud servers. We used a stack of Terraform and Helm to provision the source{d} products as well as internal workflows for machine learning and data retrieval.

In November 2019 source{d} went bankrupt.

To achieve this we developed several Kubernetes Controllers and Terraform Providers. Such as kubernetes-local-pv-provisioner, terraform-provisioner-online-rescue and terraform-provider-online.
