I have 6 years experience of deploying highly-available solutions based on Kubernetes. Due attention is paid also to security aspects of system, such as multi-layer hardening (based generally on CIS, but not only).
Also i'm writing and optimizing Terraform modules, Ansible roles, Helm charts, deploying service mesh (mostly Istio, but can be exclusions) into Kubernetes cluster(s) and/or VM(s).
Generally solving any other cloud-native based task, including ones with SysAdmin/DBA nature, DevOps/SRE nature etc.
