Hi 👋, I'm Vojtěch Mareš

Freelance DevOps Architect and Lecturer

As a Freelance DevOps Architect and lecturer, I help companies optimize their infrastructure costs, eliminate technical debt, and prepare their IT systems for rapid scaling. I specialize in Kubernetes, cloud-native technologies, and modern DevOps practices.

My services include:

  • Consulting - Analyzing your current infrastructure, identifying issues, and designing optimal solutions
  • Training & Workshops - Hands-on training with modern cloud technologies and practical examples
  • DevOps Collaboration - Long-term partnerships managing infrastructure, updates, and application requirements

Check out my website to learn more about how we can work together.

Training & Workshops

I share my knowledge through hands-on workshops covering modern DevOps tools and technologies:

  • Git - Version control fundamentals and advanced workflows
  • ArgoCD - GitOps continuous delivery for Kubernetes
  • Docker - Containerization and container orchestration basics
  • Postgres on Kubernetes - Running production databases on Kubernetes
  • Terraform - Infrastructure as Code with Terraform
  • Kubernetes - Container orchestration and cloud-native applications
  • GitHub Actions - CI/CD automation with GitHub
  • GitLab CI - Continuous integration and deployment with GitLab

All workshops include practical examples and hands-on exercises. Training materials remain available after completion.

Open Source DevOps Stack

I believe in the power of open-source technologies. With free and open-source tools, anyone can get started building modern, production-ready infrastructure. The open-source DevOps ecosystem provides everything needed to run reliable, scalable systems.

Kubernetes - The Foundation

Kubernetes ties everything together as the central platform for container orchestration and cloud-native applications. What makes Kubernetes a safe choice for your infrastructure is that it's backed by the Cloud Native Computing Foundation (CNCF), a vendor-neutral non-profit organization under the Linux Foundation. This ensures long-term stability, community-driven development, and protection against vendor lock-in.

Observability Matters

Modern infrastructure requires comprehensive observability. I work extensively with the Grafana stack (Prometheus, Loki, Tempo, Mimir) and OpenTelemetry to provide:

  • Metrics - Understanding system performance and resource usage
  • Logs - Debugging and troubleshooting applications
  • Traces - Following requests through distributed systems

Platform Engineering - The Next Step

Platform engineering is the natural evolution of the DevOps journey. While DevOps focuses on breaking down silos between development and operations, platform engineering takes it further by building internal developer platforms that enable teams to self-serve infrastructure and deployments. This reduces cognitive load on developers while maintaining operational excellence.
