What I'm looking for

I’m looking for a cybersecurity role where I can do vulnerability research and red-team testing, harden systems, and keep upskilling in a strong lab culture—especially around cloud/AI security and threat intelligence.

I’m a hands-on Cybersecurity Specialist with deep expertise in hardware reverse engineering, threat intelligence, and system hardening. I use proactive “Left of Bang” strategies and an adversarial mindset to identify and mitigate vulnerabilities before they turn into incidents.

I stay continuously sharp through active CVE research and exploit development in a dedicated home lab environment. I’ve built repeatable workflows for vulnerability research, LLM security testing, and adversarial input analysis—using tools like Burp Suite, Metasploit, Nmap, and Splunk to validate findings and improve detection engineering.

I also bring a practical systems-and-infrastructure focus: VPN and firewall management, WiFi security, MFA implementation, encrypted storage (VeraCrypt), and firmware analysis and reverse engineering. Beyond security, my background in high-accountability operations and compliance strengthens my discipline, safety mindset, and attention to detail when handling sensitive systems and processes.
