🎯 Professional Positioning

CompTIA Security+ certified enterprise IT professional with 12+ years of experience across systems, infrastructure, networking, access control, endpoint security and business-critical operations, now focused on SOC operations, detection engineering, incident response/DFIR and security automation.

My portfolio is evidence-first: professional experience, authorized independent labs, coursework and virtual job simulations are clearly separated so recruiters can understand exactly what each project demonstrates.

Security workflow: Environment → Risk → Telemetry → Detection → Investigation → Remediation → Validation

Based in Zimbabwe · Open to international opportunities and relocation
