I've conducted authorized vulnerability assessments, penetration testing, security audits, and threat research as a freelance cybersecurity agent in Nairobi. I help secure websites and networks by reviewing configurations, analyzing logs, documenting vulnerabilities, and recommending remediation.

I'm developing a sensitive-data monitoring and leak-detection system using HMAC-chained audit logs, anomaly detection, and risk scoring to identify suspicious activity.

I've also built web and data solutions, including a repair shop management system with Node.js and MySQL CRUD functionality, and contributed to an outfit recommendation AI application. My data analysis work includes cleaning, validating, and reporting on structured datasets with Excel, SQL, and Python.

I bring hands-on experience with Kali Linux, Wireshark, Nmap, virtualized lab environments, cloud tools, and full-stack development. I value structured problem solving, clear feedback, independent execution, and remote collaboration.
