How It All Began

---

My journey into the dynamic world of IT began in my teenage years, sparked by a deep fascination with computers and the intricate dance of technology. This early curiosity quickly evolved into a focused pursuit after secondary school, where I earned my CompTIA A+ certification. It was during this foundational experience that I first discovered my passion for cybersecurity.

To deepen my understanding of network security, I pursued the CompTIA Network+ certification, setting the stage for my career. My commitment to cybersecurity was further solidified with the CompTIA Security+ certification. Faced with the exciting challenge of specialization, I chose the Certified Ethical Hacker (CEH) certification, a pivotal milestone that ignited my enthusiasm for offensive security tactics. To further enhance my expertise, I earned my first Cisco Certified Network Associate (CCNA) certification in routing and switching, strengthening my foundational networking skills.

As I continued exploring vulnerabilities and emerging hacking techniques, my curiosity expanded into digital forensics. This led me to achieve the Computer Hacking Forensics Investigator (CHFI) certification, providing valuable insights into operating systems, network forensics, and investigative methodologies.

To reinforce my ability to protect organizations and secure networks, I pursued certifications in firewall operations, including CCNA Security, Check Point Certified Security Administrator (CCSA), and Fortinet. These credentials and training marked a significant transition from administrative roles to dedicated security positions, allowing me to tackle evolving cybersecurity challenges while continuously expanding my expertise.

My journey eventually led me to education and training. I began by teaching Cisco certification courses, then expanded into cybersecurity training at various institutions. This shift enabled me to collaborate on secure network strategies, develop comprehensive training programs, and educate professionals across both private and public sectors—including regional ISPs and government agencies—on cybersecurity operations and defensive tactics.
