What I'm looking for

I’m seeking a Desktop Support or Service Desk role with a clear path into cybersecurity.

At Strawberry Computers, I consulted with clients and provided first-line desktop support, resolving hardware and software problems. I resolved 90% of tech issues within 24 hours and helped increase customer retention by 25%.

In my personal labs, I triaged simulated alerts using Splunk and ELK, analyzed network traffic with Wireshark, Zeek and Brim, and investigated Active Directory threats in Windows Security and Sysmon logs.

I hold Google IT Support, IBM IT Support and Google Cybersecurity Professional Certificates. I’m building my security skills through hands-on labs and coursework, including an enterprise-wide NIST Cybersecurity assessment.
