Background

About Emmanuel Johnson

I’m a Technical Support Specialist with 3+ years of experience bridging IT support, system administration, and cybersecurity. My career started in a nontraditional way, over five years as a plumbing technician taught me to troubleshoot complex systems under pressure, think critically, and deliver solutions fast. Those same skills now drive my work in IT, where I manage cloud and on-prem environments with a focus on performance, reliability, and security. At Guilford Press, I’ve led and delivered high-impact IT infrastructure projects, including: Microsoft 365 Migration – Planned and executed company-wide transition, streamlining communication and collaboration for 80+ users. Room Finder & Workspace Booking – Deployed and configured in Outlook via PowerShell to optimize hybrid office scheduling. Exchange Online Archiving – Implemented retention and archive policies to reduce mailbox sizes and improve Outlook performance. Endpoint Security Management – Administer Microsoft Defender and enforce security policies for both Windows and Mac endpoints. Core Skills & Tools: Microsoft 365 | Azure AD | Exchange Online | SharePoint PowerShell Automation | Identity & Access Management Windows & macOS Administration | Endpoint Security Cloud Security & Threat Detection | SIEM (Microsoft Sentinel, Wazuh) While my current focus is on systems administration, my security expertise — including SOC automation and Azure honeypot projects — ensures I manage systems with both stability and threat resilience in mind. Always looking to connect with IT leaders, system admins, and infrastructure engineers to share knowledge and ideas.
