As a seasoned cybersecurity and cloud professional, I have a wealth of experience in fortifying digital infrastructures and protecting valuable assets against evolving cyber threats. With a strong background in both cybersecurity and cloud computing, I excel in architecting robust security solutions tailored to meet the unique needs of modern organizations.
