What I'm looking for

I’m seeking work as a Linux Systems Administrator or Infrastructure Engineer focused on mission-critical environments, high availability, security, hosting, and hybrid infrastructure (on-premises and cloud), preferably remote.

At BRHosp.com.br, I administer and maintain Linux hosting infrastructure in production, including servers responsible for hundreds of active domains.

I manage web services, databases, and email, and administer WHM/cPanel environments. I also maintain firewall and security policies using iptables and CSF.

For monitoring, I use Grafana, Prometheus, Nagios, and Munin. I diagnose critical incidents and work to minimize downtime through rapid response.

Earlier, at Arew Sistemas e Informática, I installed and administered Linux servers, managed MySQL databases, and implemented encrypted private networks using OpenVPN.
