What I'm looking for

I am looking for a role that fosters growth, encourages innovation, and values security best practices.

I am a dedicated cybersecurity engineer with hands-on experience in defensive operations, phishing detection, incident response, and security awareness training. My journey in cybersecurity has equipped me with the skills to conduct real-time log analysis, manage network defenses, and oversee vulnerability management using industry-standard tools such as Wireshark, Splunk, AWS, Nessus, and Kali Linux. I am committed to proactive threat hunting and maintaining security hygiene in alignment with global standards.

In my current role as a Security Consultant at Sterlingtech Group, I have successfully conducted security audits and awareness programs that resulted in a 35% reduction in phishing click rates across client-facing teams. My previous experience as a Cybersecurity Intern at MICTU allowed me to support system hardening and basic digital forensics, improving endpoint resilience and response time during incidents by 30%. I take pride in my ability to correlate data from various sources to detect and respond to security threats effectively.
