What I'm looking for

I seek a collaborative, security-focused role in cybersecurity research or threat hunting where I can work on cutting-edge projects, perform penetration testing, and grow technical expertise while contributing to team-led incident response and defensive initiatives.

I am a computer and software engineer specialized in cybersecurity, investigations, cyber defence, and ethical hacking, with practical experience implementing defensive mechanisms across networks, firewalls, intrusion detection and protection systems. I have strong hands-on experience with Linux servers, CSI Linux, automation with Python, bash scripting, network protocols, databases, and security standards such as NIST-CSF, and I work continuously on certifications to deepen my expertise.

I bring incident response, disaster recovery, access control knowledge and familiarity with SCRUM-AGILE tools like JIRA and Confluence, plus leadership experience coordinating teams to address malware, brute-force attacks and data leaks. I am eager to contribute to cutting-edge cybersecurity research, penetration testing and protection of systems, networks and digital assets within a collaborative, security-focused team.
