What I'm looking for

I'm seeking a fully remote international cybersecurity role focused on web application security, API security, vulnerability research, and penetration testing. I'm particularly interested in Security Analyst, Application Security Engineer, Product Security Engineer, and Vulnerability Researcher positions.

I'm a cybersecurity researcher and bug bounty hunter specializing in web application security, API security, cloud security, vulnerability assessment, and responsible disclosure.

My experience includes reconnaissance automation, attack surface discovery, vulnerability validation, security testing, and proof-of-concept development. I work with tools including Burp Suite, Nuclei, Katana, Subfinder, FFUF, and custom Python and Bash scripts.

I'm interested in remote international opportunities in Application Security, Product Security, Vulnerability Research, and Security Analysis, where I can help organizations identify and remediate security weaknesses.

I'm committed to ethical security research, clear technical reporting, and practical remediation guidance. I'm open to globally distributed teams and opportunities that value hands-on security skills and measurable results.
