What I'm looking for

I'm seeking a remote cybersecurity role where I can monitor and investigate alerts, analyze phishing and malware threats, conduct vulnerability assessments, and grow through hands-on SOC and incident response work.

At CyberNow Labs, I monitored real-time alerts in Splunk and QRadar, investigated phishing and malware incidents, and escalated critical threats for immediate action. I documented more than 50 vulnerability findings with Nessus and Tenable.io, improved threat detection accuracy by 30%, and helped increase incident resolution speed by 20% using SentinelOne and CrowdStrike Falcon.

I also build responsive front-end solutions at Joe Solve and previously developed React web applications for Christex Foundation. I'm ISC² Certified in Cybersecurity and CompTIA Security+ certified, with a First-Class B.Sc. in Software Engineering with Multimedia.
