IT Desktop Support Engineer → Cybersecurity | CompTIA Security+ Certified


👋 Who I Am

IT professional with 2+ years in desktop support making a deliberate move into cybersecurity. I hold a CompTIA Security+ and have built everything in this portfolio through hands-on labs not just coursework.

My hands-on labs cover the full security operations lifecycle: SIEM deployment, threat detection, vulnerability management, incident response, threat hunting, web application security, cloud IAM, and GRC policy development all built in Azure cloud and on-premises environments.
