Tätigkeitszeitraum

8/2017 – 4/2020

Tätigkeitsbeschreibung

I helped inovex GmbH to open a new revenue stream while reducing IT infrastructure costs.

On the technological level it means a heavily integrated, turnkey solution to roll out OpenStack installations from scratch, complete from bootstrapping on bare metal, through fully-automated provisioning, to deploying log analytics, monitoring and metrics collection with a single push of a button.

I also helped to enable the company's customers to gain new IT capabilites through automation of datacenter operations. It means building an inventory based on NetBox, provisioning VMware virtual machines with Terraform, and automating deployment with Ansible. All those elements are also integrated together with GitLab CI pipelines for continuous integration and delivery for infrastructure.

Linux (Kernel), Cloud (allg.), Systems Engineering, Ansible, Puppet

Tätigkeitsbeschreibung

I helped adjust GmbH to scale their early infrastructure through automation, and enabled backend and integration engineers to make sense of huge amounts of logs and metrics in a self-service fashion.

My main responsibilities were to design and build a high performance ELK stack (processing more than 300k eps with total data size over 1 PB), to maintain and extend high performance monitoring systems (Graphite+Grafana), and to improve data center automation with Rex in a Gentoo-only environment.

I also introduced weekly "Friday talks" as an internal knowledge sharing platform from scratch, maintained the company's tech blog, organized a couple of meetup events, and gave talks about some parts of the technology stack at various conferences.

Über mich

I'm an experienced Linux engineer with a strong focus on software development. My main interests are the DevOps culture, infrastructure automation and automated testing. On top of those, I find system integration projects highly rewarding.

I'm also a free/libre/open source software activist contributing to various projects, and organizing Open Source Contribution meetups regularly. I offer consulting, training and sponsored development services for the (R)?ex automation framework as a core developer.

I'm an autodidact, who enjoys learning new things out of curiosity. I'm honored to be a teacher sometimes, but I always consider myself as a student. From time to time, you can find me speaking at different conferences and workshops. I have a few posts published on my personal blog, on big-elephants.com, and on perlmaven.com, but most of the content I create are documentation for various projects.
