Cybersecurity engineer transforming from successful hospitality management to tech, bringing unique perspectives on system reliability, crisis management, and user experience. Currently building AI-powered automation systems while preparing for OSCP certification.
🚀 What I Bring to the Table#
Unique Value: I debug systems like I debug recipes – methodically, creatively, and with an eye for what users actually need. My 7+ years in high-pressure customer environments taught me that the best security is invisible to users but bulletproof against threats.
