What I'm looking for

I seek roles where I can lead incident response and security audits, mentor teams, implement proactive defenses, and grow in a collaborative, compliance-focused environment.

I am a Cyber Security Analyst with over four years of hands-on experience safeguarding organizations from cyber threats and improving security posture.

I have led real-time security monitoring and incident response using tools such as Splunk, IBM QRadar, Microsoft Sentinel, ELK, Nessus, OpenVAS, Check Point and Fortinet FortiAnalyzer, and conducted forensics with Autopsy.

In roles at Kenya Revenue Authority and Kenya Women Microfinance Bank I performed system security audits, risk assessments, compliance monitoring (ISO/IEC 27001), vulnerability assessments, and developed incident response procedures and security baselines.

I also mentor and teach secure coding and cybersecurity practices, delivering training in Python, JavaScript, HTML, CSS, PHP, Java and database security, and I continually research emerging threats and defensive technologies to strengthen organizational resilience.
