About Me
I am a Cisco Certified Network Associate (CCNA) and final-year cybersecurity student focused on Network Defense, Cloud Security Architecture, and Applied Cryptography.
My work bridges the gap between theoretical security models and practical infrastructure hardening. Unlike typical academic tracks, I focus on applied research: building practical defense tools, analyzing live network traffic, and documenting vulnerability patterns.
