Seif O.

Cybersecurity professional who uniquely combines deep system administration expertise with comprehensive security operations and active web application security research. Proven ability to deploy and maintain enterprise security infrastructure (Elastic Stack, Splunk, pfSense) on Linux systems while conducting advanced threat detection and incident response. As an active bug bounty hunter on HackerOne, I bring real-world offensive security experience in discovering and exploiting OWASP Top 10 vulnerabilities across diverse web applications. Strong networking foundations in subnetting, VLANs, and traffic analysis enable me to secure organizations from both the infrastructure and application level—delivering end-to-end security coverage that spans network, system, and application layers. This rare combination of defensive SOC operations, infrastructure management, and active offensive security research allows me to think like an attacker while building robust defensive systems and optimizing security architecture for real-world threat scenarios.
