- Large-scale Cassandra Clusters (up-to 30 nodes)
- Public and private clouds (VMware, AWS, GCP)

I used to automate my work with a variety of tools such as:
Python, Ansible, Puppet, Terraform, etc.
(Actually, tools aren't important; important the fact that I really keen on automation of my work)

My Monitoring experience comprise:
- Zabbix
- Nagios (icinga2)
- Prometheus (+Thanos and/or Victoria Metrics)
- Pingdom
- GCP uptime checks, cloud functions (or AWS lambdas) and other kind of blackbox monitoring

Windows-based systems are not my cup of tea:)
