What I'm looking for

I am looking for a role that challenges my skills in cybersecurity and allows for continuous learning and growth.

I am a dedicated cybersecurity specialist with extensive experience in DevOps, focusing on the security of embedded devices and server infrastructure. My journey has led me to specialize in red-team security assessments, where I simulate real-world cyberattacks to identify vulnerabilities in various systems. I have successfully managed complex security audits, acting as the primary client contact and delivering insightful reports to stakeholders.

Throughout my career, I have performed security assessments on IoT devices, conducted source code reviews, and executed penetration testing using a variety of tools. My passion for technology extends to developing internal tooling and services, as well as spear phishing campaigns that leverage my background in email marketing. I am committed to enhancing security practices and promoting awareness of potential threats in the digital landscape.
