Sebestyen Reti

IT Support & Infrastructure Coordinator with close to 5 years of hands-on experience in fast-paced, multilingual corporate environments. I specialize in Microsoft 365 administration, hybrid Active Directory, Azure, network troubleshooting, and cybersecurity fundamentals — from tenant security policies and identity management to full cloud and telephony migrations (on-premise to cloud backup, legacy PBX to Microsoft Teams, SharePoint Online rollout). Day to day, I handle first- and second-line technical support, onboarding/offboarding, hardware lifecycle management, and vendor coordination, while also leading infrastructure projects: disk encryption rollout, cloud-managed antivirus migration, centralized patch management, and security-awareness training programs including phishing simulations. I also have hands-on experience with VoIP/telephony platforms, audio-visual system setups, and CCTV, alongside broad exposure to Windows and Apple environments. Certified CompTIA A+ and Microsoft 365 Administrator (MS-102), with working knowledge of TCP/IP, DNS, DHCP, subnetting, and network security best practices. Based in Zurich, Switzerland (CET), I'm comfortable working evening and night shifts to overlap with US business hours. Fluent in English, with working German, French, Romanian and Hungarian — useful for supporting multilingual or distributed teams. Looking for remote IT support, systems administration, or M365/cloud-focused roles where I can apply this troubleshooting and infrastructure background to a distributed team, including part-time or overnight coverage positions.
