Samuel Ajayi

Security engineer with 5+ years of hands-on experience across penetration testing, application security, cloud infrastructure, containerized environments, security automation, and vulnerability assessment. Experienced in building and operating security-focused platforms on AWS, with practical engineering across Docker, Linux, networking, VPN infrastructure, reverse proxies, backend systems, and PostgreSQL. Strong offensive-security background combined with a builder mindset, focused on integrating security into infrastructure, development, and deployment workflows.

Over the years, I've discovered and reported critical vulnerabilities in live web environments, led multiple cybersecurity awareness campaigns that significantly reduced human error-related risks, created beginner-to-intermediate vulnerable virtual machines like MediLabs NG, launched a 30-Day Practical Pentesting Mentorship Program, and used storytelling and relatable analogies to make cybersecurity less intimidating and more accessible for individuals starting in the field and in environments where digital literacy is still evolving.
