Hi, I’m Charlton Omondi
a Cybersecurity Analyst. Penetration Tester. Web App Developer. Mobile App Developer. Security Researcher. Security Consultant. Security Engineer. Ethical Hacker.

Conduct internal and external penetration tests against web applications, network infrastructure, and wireless environments to identify vulnerabilities before adversaries can exploit them. Develop and execute custom exploit chains using Kali Linux tools (Metasploit, Nmap, Burp Suite, Wireshark) to demonstrate risk scenarios and validate findings. Perform social‑engineering assessments (phishing simulations, vishing calls) to gauge organizational readiness and user awareness. Collaborate with development and operations teams to remediate critical weaknesses—resulting in a 60% reduction in medium‑and‑high severity vulnerabilities over six months. Produce detailed technical reports and executive summaries, presenting actionable recommendations to C‑level stakeholders and driving security policy enhancements.

Designed and developed a full-featured fleet management system to track vehicles, fuel usage, maintenance schedules, and trip logs using PHP (Laravel), MySQL, JavaScript, HTML5, and CSS3. Built and deployed the company website using PHP Laravel, ensuring mobile responsiveness and fast load times to improve online visibility and client engagement. Integrated dynamic features such as modals, real-time data tables, and analytics dashboards to streamline internal logistics and reporting. Implemented secure authentication, role-based access, and system account controls for fleet administrators and staff. Performed database optimization and introduced system logs and alerts to ensure performance, reliability, and proactive issue detection.
