ArmeniaWhat I'm looking for
I’m an IT Systems & Technical Support Engineer with 6+ years of experience providing technical support, managing Microsoft 365 environments, Windows systems, and IT infrastructure. I focus on resolving complex issues, keeping services stable, and supporting teams across the EMEA region.
In my current role as a System Engineer, I administer Microsoft 365 services—Azure Active Directory, Exchange Online, Microsoft Teams, and SharePoint Online. I configure and provision laptops for new employees, deliver IT onboarding and induction sessions, and monitor Microsoft 365 services, Windows systems, and security events to maintain operational stability.
I also manage endpoint protection, IT assets, vulnerabilities, and security compliance. I design and deliver cybersecurity awareness training for EMEA employees, covering phishing prevention, password security, safe internet usage, and data protection best practices, and I’ve delivered this training twice a year.
Previously, I worked as a Senior Technical Support Engineer, where I resolved incidents through phone, email, chat, and ticketing systems, and led onboarding and technical training for new support engineers. I’m currently preparing for the Microsoft Azure Fundamentals (AZ-900) certification to deepen my cloud infrastructure expertise.
