What I'm looking for

I am looking for a role that offers growth opportunities in cybersecurity, where I can apply my skills in penetration testing and incident response while collaborating with a dynamic team.

Cybersecurity Professional with expertise in both offensive and defensive security.

I work in cybersecurity with a focus on both defending systems and finding their weak spots before attackers do. Over the years, I’ve had the chance to explore many sides of this field; from investigating incidents and monitoring threats, to testing applications and networks for vulnerabilities.

What I enjoy most is bridging the gap between technical details and real-world impact: helping teams, clients, and stakeholders understand risks clearly and take action.

Cybersecurity is constantly changing, and so am I -> always learning, always curious, and always ready to take on new challenges.
