I'm engineering manager in a cloud-native world managing mid-sized cross-functional team at VirtusLab.

These days I usually build cloud platforms and help with large transformation in area of cloud-native. I'm still actively involved in technical design and programming.


  • Software Engineering - mostly Go these days, previously Java, Python.
  • Building cloud infrastructures and platforms - Kubernetes, AWS, GCP, Azure, VMWare Tanzu
  • Service Mesh and inter-service communication - general understanding of concepts and various technologies like Consul Service Mesh and Istio - still someting to expore more.
  • Infrastructure as Code - quite good experience with doing this at scale, including inner-sourcing approach.
  • Monitoring and Incident Management - open source technologies like Grafana & Prometheus as well as enterprise products like Splunk, Datadog, etc.
  • Continuous Integration and Delivery
  • Establishing support and operations for live systems

Notable Work

  • Built self-hosted production-ready Kubernetes distribution based mostly on CoreOS stack on AWS. Full lifecycle-management with immutable infrastructure using CloudFormation, Bash, cloud-init and Container Linux.
  • Designed, built and supported container as a service platform based on self-hosted Kubernetes on AWS. The platform was hosting bussiness-critical services for 3+ years until managed Kubernetes became mainstream.
  • Responsible for Kubernetes infrastructure standards, best practices and infrastructure as code written in Terraform within large organization (200+ devs).
  • Successful inner-sourcing initiative in area of cloud infrastructures, mainly in Azure. Built an active community and contribution model.


  • You can find some of my blog posts on I'm wring mostly on software enginering, management and cloud-native technologies.
  • Also rambling on Twitter @antoniaklja.
