Cybersecurity & Ethical Hacking Expert

I specialize in ethical hacking, digital defense, and vulnerability assessment with a focus on proactive risk mitigation.

Offensive & Defensive Threat Hunting Red Teaming Vulnerability Research

My priority is to identify and reduce risks before they are exploited. I am committed to protecting digital assets and anticipating adversarial tactics to stay ahead.

Beyond security, I have a solid software engineering background. I design Python- and Rust-based tools for automation, threat intelligence, and SIEM optimization — delivering efficient, resilient, and intelligent defense solutions.

I've been pursuing this journey with passion since 2022.
