What I'm looking for

I’m looking for an ethical, hands-on security role where I can test web and network environments, automate reconnaissance, and learn from real detection-and-response workflows while contributing measurable risk reduction.

I’m a penetration tester and ethical hacker focused on offensive security and vulnerability research, with a strong commitment to ethical, lawful testing that reduces real-world risk. I combine security fundamentals with programming to simulate realistic attack chains and evaluate detection and response capabilities.

I’ve built capability through Cisco and Opecstat cybersecurity learning paths and certifications, strengthening my understanding of threat landscapes, attack vectors, and defensive controls. I can conduct basic network and web application assessment, including analyzing code for security flaws and focusing on OWASP Top 10 issues like XSS and insecure forms.

I leverage Python (along with C and HTML) to develop custom tools and automate reconnaissance workflows. I also analyze network traffic and system logs to detect simulated attacks, reinforcing Blue team awareness while applying offensive thinking to improve security outcomes.

My approach is practical and measurement-driven: I use what I learn to improve security posture through repeatable testing, clear findings, and actionable recommendations. I’m currently pursuing BSc Cybersecurity (in progress) to deepen my expertise and consistently grow into higher-impact security roles.
