Background

About Oliver O.

I work across both user facing issues and infrastructure operations, helping maintain the reliability, security, and day to day functionality of IT systems. My experience includes managing Microsoft 365 and Active Directory user accounts, access, and permissions, as well as supporting Windows systems and resolving Tier 2 technical issues.I am actively involved in improving email security through filtering, quarantine tuning, and policy refinement, and I create and maintain internal IT documentation and standardized procedures. I also perform hands on infrastructure work, including racking servers, installing networking equipment, and running Ethernet cabling.I hold multiple CompTIA certifications, including Security+, Network+, and A+, and consistently look for opportunities to automate repeatable tasks to improve system reliability and streamline operations, with a focus on continued growth in Systems Administration and IT Infrastructure roles within environments that value learning and security minded operations.
