What I'm looking for

I'm seeking a Cybersecurity Analyst or Software Engineer role where I can apply security fundamentals and full-stack development skills to build and defend real-world systems.

I'm building RoleGuard AI, an automated broken access-control scanner using Python, FastAPI, Playwright, and OWASP ZAP. I also designed a secure ICT ticketing platform with RBAC, authentication, TLS, logging, email verification, password recovery, and two-factor authentication.

As a MUST Cyber Security Club member and Intervarsity CTF participant, I ranked #5 individually while my team placed #4 in Kenya. I'm pursuing a BSc in Computer Security and Forensics and apply hands-on skills in penetration testing, digital forensics, secure software development, and AI-driven risk assessment.
