I look after the infrastructure that keeps systems running — servers, networks, monitoring and security — and I am taking that towards data, with machine learning applied to monitoring.
What I do

FortiGate and FortiClient, UniFi and Ubiquiti, firewalls, IDS/IPS, VPN, SSH access management, DNS zones and email authentication.
Monitoring and Automation
Zabbix, Prometheus and Grafana for proactive monitoring, with backup, deploy and maintenance automated in Shell Script.
