About Greshan Bovithanthrige

Experienced Infrastructure Engineer with a strong technical background in cloud computing, cybersecurity, and enterprise IT solutions. I specialize in Microsoft 365, Windows Server, Azure, and Google Workspace administration, delivering high-availability environments with robust security and compliance frameworks. My expertise covers full-stack Microsoft 365 administration (Exchange Online, Teams, SharePoint, OneDrive, Intune), hybrid AD and Azure AD deployments, and complex email infrastructure troubleshooting. I manage security-driven implementations with Barracuda Cloud-to-Cloud Backups, EGD, Impersonation Protection, and SMTP journaling, ensuring resilient cybersecurity postures. With deep hands-on experience in Windows Server (AD, GPOs, DHCP, DNS, Hyper-V) and cloud networking, I architect and optimize IT environments for performance, scalability, and security. I oversee enterprise-grade antivirus deployment and policy enforcement, streamline VoIP solutions (NFON, MS Teams), and manage network security with FortiGate firewalls and DrayTek Vigor L2/L3 switching. Proactive monitoring, SLA-driven incident resolution, and compliance with Cyber Essentials Plus, ISO 27001, and GDPR are core to my workflow. I also develop technical documentation, internal WIKI resources, and best practices for IT operations. Passionate about automation, cloud security, and high-availability infrastructure. Always looking to innovate and enhance IT ecosystems to drive efficiency and resilience. Let’s connect!
