@timothybest
System Administrator and cybersecurity-minded IT professional with 8+ years securing networks, troubleshooting systems, and supporting customers.
What I'm looking for
I’m a seasoned information technology professional with over eight years of experience specializing in system administration and customer support. I configure, manage, and troubleshoot servers, networks, and storage systems, with a strong focus on network administration, security protocols, and infrastructure management. I’m also Security+ certified and currently hold a Secret clearance.
Across roles, I’ve handled incident response planning, application security, and IT risk management—conducting risk assessments and vulnerability scans, implementing cybersecurity measures like encryption, access controls, and intrusion detection systems, and supporting disaster recovery readiness. From help desk and Active Directory account management to enterprise backup solutions and security clearance support, I prioritize accurate records, HIPAA-compliant handling of sensitive data, and clear communication with cross-functional teams and stakeholders.
