My fascination with computers began in my teenage years, drawn to the intricate dance of technology. After secondary school, I launched my IT journey with a CompTIA A+ certification, where I first discovered my passion for cybersecurity. This interest led me to pursue the CompTIA Network+ certification, deepening my understanding of network security and setting the stage for my career in IT security.
Determined to build a strong foundation, I obtained the CompTIA Security+ certification, which solidified my commitment to cybersecurity. Faced with the decision of specialization, I chose the Certified Ethical Hacker (CEH) certification, a pivotal milestone that fueled 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 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, which provided 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 marked my 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, where I began teaching Cisco certification courses before expanding into cybersecurity training at various institutions. This shift enabled me to collaborate on secure network strategies, develop training programs, and educate professionals across private and public sectors—including regional ISPs and government agencies—on cybersecurity operations and defensive tactics.
