About Me

I'm Joseph

Application Security & DevSecOps Engineer

I am a cybersecurity professional with 3 years of experience in Application Security, DevSecOps, and penetration testing. I hold a Master’s in Cybersecurity from the University of Maryland and specialize in securing applications, conducting vulnerability assessments, and integrating security into CI/CD pipelines. I have hands-on experience with tools like Microsoft Sentinel, CrowdStrike Falcon, Burp Suite, and Veracode, and have worked on both offensive and defensive security projects. Passionate about blue teaming, cloud security, and secure coding, I aim to continuously enhance my skills while helping organizations strengthen their security posture.
