What I'm looking for

I seek a dynamic role in cybersecurity that fosters growth and innovation.

I am a dedicated cybersecurity professional with extensive experience in penetration testing and red teaming. Currently, I work as a Pentester at Logicalis Portugal, where I conduct external, internal, and physical audits, focusing on mobile and web applications. My role involves designing and implementing red team architecture and creating various phishing campaigns. I take pride in my ability to produce comprehensive reports using tools like GhostWriter and Microsoft Word, ensuring that my findings are communicated effectively.

Previously, I served as a Cyber Security Analyst at Layer8, where I honed my skills in conducting audits and developing phishing campaigns. My journey in cybersecurity began as an Offensive Cyber Security Analyst at Artresilia, where I contributed to infrastructure development and automated processes to enhance efficiency. My background in IT support and hardware repair has equipped me with a solid foundation in technology, allowing me to approach challenges with a unique perspective.
