Kojo Ewusi Mensah

I’ve been a Lead Mobile Engineer at ECFATUM in Accra, implementing secure authentication and authorization, running security reviews, and remediating vulnerabilities while managing secure deployment pipelines and cloud infrastructure.

Before that, at FOCUS PPC as a Mobile Engineer, I built secure mobile applications and backend integrations, did root-cause analysis for production issues, and worked with APIs, databases, and infrastructure services alongside operational monitoring and reliability.

As a freelance Security Consultant, I conduct vulnerability assessments for web and mobile applications, perform security reviews using OWASP methodologies, and deliver technical findings and assessment reports. I also help clients with secure software development practices.

My MSc work fed directly into what I do day-to-day—digital forensics research involving evidence collection, log analysis, and incident reconstruction—plus hands-on projects like Python-based security automation and application security testing with tools like Burp Suite and OWASP ZAP.
