@oraclesamuel
Cyber-security engineer and instructor delivering hands-on training and robust network protection.
What I'm looking for
I am a cyber-security engineer and instructor with extensive experience designing, developing, and deploying IT infrastructures, migrating legacy systems to modern platforms, and implementing cloud solutions to increase efficiency and reduce costs. I have taught and developed cybersecurity and networking curricula, led hands-on labs using tools like Metasploit and Nmap, and guided students toward certifications and real-world skills.
Across multiple roles I improved operational uptime, developed troubleshooting protocols that improved response time, built robust firewalls and backup procedures, and continually updated course material to reflect evolving threats and best practices. I hold a B.Sc. in Computer Science and certifications in Linux and Oracle Database Administration, and I seek to apply my technical and teaching experience to strengthen organizational security and team capability.
