What I'm looking for

I'm looking for a security operations role where I can monitor and investigate alerts, build and tune detections, hunt threats, and strengthen incident response through clear playbooks and collaborative remote work.

I've monitored and triaged Windows and Linux security events at Jollof Science using Splunk, Elastic, and Wazuh, investigating alerts through closure and tuning rules to reduce false positives.

I've deployed Wazuh, written custom detection rules, hunted threats with Osquery, and mapped adversary behaviour to MITRE ATT&CK. I also create incident response playbooks, escalation procedures, and SIEM runbooks aligned to NIST Incident Response phases.

My work also includes web penetration testing at Ink Heart, where I assessed applications against the OWASP Top 10 and worked with developers to verify remediation. I publish hands-on Wazuh, Suricata, and SOC workflow guides on my technical blog.
