At 123Seguro, I automated deployments, inventory management, and state management across Linux and Windows servers using SaltStack. I also managed the office network, corporate VPNs, Wi-Fi, and IP telephony, maintaining 99.5% operational uptime.
I handled complex technical tickets in Jira Service Desk across a multi-site environment, maintaining SLA compliance above 98%. I also performed preventive maintenance, hardening, and configuration for Linux and Windows 10/11 systems.
At Harding's Holding, I designed and implemented Grafana dashboards to monitor network and server metrics, helping identify and resolve bottlenecks. I provided Level 2 support for SAP Cloud Business One and worked on network topologies and firewalls.
At Lidotel Boutique, I led a two-engineer technical team responsible for infrastructure, firewalls, and high availability. I also oversaw mission-critical servers and Opera ERP systems, including backup policies and disaster recovery plans.
