Zecharias Firew

I’m a dedicated IT Systems Engineer with over 3 years of experience supporting enterprise environments, specializing in Windows Server infrastructure, Active Directory, Office 365, Group Policy, and PowerShell automation. My work has spanned both the public and private sectors, including roles supporting federal agencies like the U.S. Department of the Treasury, where I provided hands-on engineering, troubleshooting, and systems administration for a large, high-security environment.

My core strengths lie in managing and optimizing Microsoft ecosystems, streamlining user provisioning through custom PowerShell scripts, resolving permission and access issues, and maintaining uptime and compliance across critical systems. I’ve worked extensively with SCCM, Ivanti, and Dell Avamar for patching, software deployment, and endpoint protection. I also have hands-on experience in server migrations, domain restructuring, and supporting hybrid Exchange environments.

Clients appreciate my ability to quickly diagnose and resolve technical problems, whether they’re related to hardware, software, networking, or user access. I approach each project with a strong sense of ownership, attention to detail, and commitment to reliability and efficiency. Whether it’s building out a new GPO structure, implementing a better onboarding workflow, or troubleshooting a DNS/firewall conflict, I deliver solutions that work and scale.

I’m also comfortable working across hybrid environments and remote support setups. I’ve successfully collaborated with cross-functional teams, led small-scale infrastructure projects, and trained junior technicians on best practices. My communication skills allow me to translate technical issues into clear, actionable items for both IT staff and non-technical stakeholders.

Currently, I’m offering freelance support to organizations that need help with Windows infrastructure, Active Directory cleanup or redesign, Office 365 administration, PowerShell scripting, or general system troubleshooting. Whether you need part-time support, help with a migration, or emergency response for critical issues, I’m equipped to deliver reliable, high-quality IT services with minimal ramp-up time.
