What I'm looking for

I’m seeking a SOC Analyst or Security Analyst role where I can apply log correlation, alert triage, detection engineering, threat hunting, and incident response skills in a production security operations environment.

I've built SOC home labs that use Splunk, Sysmon, Wireshark, Snort, pfSense, Active Directory, and MITRE ATT&CK to investigate brute-force activity, malware execution, lateral movement, and unauthorized access.

At Kings Builder Limited, I managed IAM and least-privilege access for a Windows Server-hosted ERP system, configured VLAN segmentation and firewall policies, and performed patch management and endpoint hardening. I also supported network and access controls across three sites at Simply Fresh Tanzania.

I've taught networking, system administration, and foundational security concepts as an Assistant Lecturer, and I’m seeking a SOC or Security Analyst role focused on log correlation, alert triage, threat hunting, and incident response.
