What I'm looking for

I’m looking for a security role where I can lead endpoint incident response with CrowdStrike and SentinelOne, support audits, and strengthen endpoint and network defenses through monitoring, configuration, and rapid stakeholder escalation.

I’m an IT and network security professional with 6+ years’ experience across telecom infrastructure, endpoint security (EDR), and IT support operations. I analyze and respond to threats and incidents using CrowdStrike Falcon and SentinelOne, while also handling network monitoring and configuration with tools like Fortinet and router/firewall platforms from Fortinet, Mikrotik, Huawei, ZTE, and FiberHome.

In client-facing environments, I align stakeholders, manage updates, support security audits, and drive process improvements under tight deadlines and escalation pressure. I’ve also supervised on-site teams as a technical contract supervisor, monitored and managed complex ticket flows with Zabbix/Grafana and GLPI, and participated in network implementation POCs for large-scale deployments.
