Hi, my name is

Sebastian.

Passionate about the job I do.

System administrator. Infrastructure architect. Problem solver.

About Me

I’m an infrastructure architect with over a decade of experience in creating high available and resilient infrastructure. I live Infrastructure as Code with a great passion. Learning new things is what motivates me and finally solving a difficult problem is satisfaction. Always giving my best is mandatory but I also understand when it’s time to be pragmatic. Often times done is better than perfect.

Here are a few technologies I've been working with recently:
  • ceph
  • puppet
  • terraform
  • ansible
  • AWS services
  • Python
  • Gitlab CI
  • prometheus
  • grafana
  • loki
  • OpenStack

Experience

Ceph Engineer - adyen N.V
April 2023 - Present

I work as a Ceph Engineer at Adyen, where I am responsible for designing and maintaining highly available, scalable storage systems.

From architecting cross-datacenter replication strategies for Ceph clusters to managing the needs of hundreds of S3 users, I ensure our distributed storage infrastructure remains robust and efficient. This includes overseeing the health and performance of multi-petabyte Ceph clusters, fine-tuning configurations, and staying on top of evolving challenges.

Adyen consistently pushes me to expand my expertise and adapt to new complexities.

Infrastructure Architect - cc cloud GmbH
Aug 2018 - 2023

I served as an Infrastructure Architect at cc cloud GmbH, a subsidiary of codecentric AG, where I was responsible for overseeing the full range of infrastructure needs.

This role encompassed a diverse array of tasks, from designing and implementing a fully automated Atlassian-as-a-Service solution to managing network infrastructure and administering the SSO system. My responsibilities also extended to providing support and guidance to colleagues whenever needed.

At cc cloud, I was consistently challenged to acquire new skills and refine existing ones. The dynamic nature of the environment ensured that each day presented unique challenges and opportunities for growth.

System administrator - METRO SYSTEMS GmbH
Jan 2012 - Aug 2018

After i finished my apprenticeship at METRO SYSTEMS I worked at they linux system administration department and was responsible for maintaining and designing their server infrastructure. Managing HP Bladecenters was as much part of this job as automating the installation of Red Hat Linux systems.

During my time at METRO SYSTEMS I was given the chance to be part of their SAP insourcing, being responsible to supply hundreds of SUSE Linux for SAP VMs and blades to othe project members.

My final steps at METRO SYSTEMS involved designing their on premise OpenStack cloud environments. Starting from ground up I designed their first environment using SUSE Cloud 5. After SUSE decided to deprecate their cloud offerings, we switched to using OpenStack ansible to set up multiple installations around the globe.
