What my clients say about me.
Long-term cooperation
When we first met Vojta, we were in the process of migrating existing Kubernetes clusters to new, improved (in-house) infrastructure packages. We were a great match in terms of automation — both for creating/tearing down infrastructure and for deployment automation — as well as in the technologies we used (AWS, Kubernetes, Terraform, Python, GitLab, Docker). Vojta designed and built new Terraform repositories for us, helped train our team and junior colleagues, and was available long-term to resolve ad-hoc issues.
Long-term cooperation
Over the past few years, Vojta Mareš and I have successfully tackled many technical challenges, primarily in the world of Kubernetes, where Vojta excels from both an operations and development perspective. Together we automated processes with scripts such as GitHub Workflows and GitLab pipelines, and handled complex infrastructures for public clouds (AWS, GCP) as well as our own RKE2 clusters with high-availability coverage. Vojta’s expertise extends into development too — his cross-disciplinary skills enabled us to build the foundational concept of a Kubernetes operator in Go, which is a key component of our product. Thanks to his experience and ability to quickly learn new things, the world of Kubernetes is an open book to him, and very little can catch him off guard.
GitHub Actions training
Mr. Mareš provided us with excellent training on pipelines, CI/CD, and hands-on demonstrations with real-life examples based on his extensive experience in DevOps. We have both senior DevOps people and beginners on our team, and the content and format of his training was suitable for both groups — thumbs up.
Git & GitHub training
We learned a great deal about how Git works under the hood, with real demonstrations of operations (including less common ones) both in the command line and in tools like GitHub Desktop. It was useful to see the most efficient ways to work with Git and how it all fits into our team’s daily workflow through GitHub Enterprise, which we use at our company.
Let’s do this together
It’s time to bring your infrastructure up to current standards. Infrastructure should present your application to the world, not hold it back.
