Enabling high performance IT systems and software delivery for rapidly growing organizations.

Highlighted achievements for previous customers:

- Reduced physical infrastructure TCO and complexity by 75%.
- Reduced the monthly infrastructure cost by a comparable amount to my own consulting fees.
- Reduced recurring infrastructure costs by 10%, build resource usage by 60x, and server provisioning delay by 10x.Enabling high performance IT systems and software delivery for rapidly growing organizations.

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 operation. 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.

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.
