Position: Linux system engineer
Category: Sysadmin
English level: upper
Years of experience: 11


Experience in hosting company last five years in it-director position.
Complete experience with system administration more than 12 years. 

I have experience in:
project, setup, maintenance and deploy with kvm virtualization on high workloads.
project, setup, maintenance and deploy with xen virtualization on high workloads.
project, setup, maintenance and deploy with hyper-v virtualization on high workloads.

Automatisation all workflows in different solutions - ansible, pure programming languages (python/php), shell languages (bash/powershell)
Excellent experience in bash, python, powershell scripting.

I respect a monitoring systems with many metrics and logging any action. This give a change to solve any problem and prevent it in future.
I'm works with prometheus stack (prometheus, alertmanager and many metric exporters, also I develop my own exporters metrics).
In past i'm works with TICK stack, but with time i'm migrate all infrastructure in hosting to prometheus. This give me a more opportunities for alerting and analysing.
For visualize metrics i'm use grafana - this very fast, simple, and beautiful.
For logging we use centralized log store server.

About virtualisation system i can says next:
xen - rather dead than alive, and we abandoned him.
hyper-v - only for windows systems. *nix have some troubles.
kvm - my favorite hypervisor. It can complete very many cases.
Starts from simple development environment and ends with very big clusters, or can passthrough hardware devices from host to guest systems without problems. It have very good performance for fully virtualisation system.

Also i have experience with docker, docker-compose, docker-swarm, systemd-namespaces.
This is very good solutions in some cases. In many some cases)

lamp / lemp stacks - experience from setup to debug any problems (error, performance and others). This is very easy for me.

And of course excellent experience in any linux distributive.
