At Ghana Police Headquarters, I monitored network traffic and security events using SIEM tools, and worked on intrusion detection systems to identify suspicious activity. I also investigated network logs, packet captures, and memory dumps to help reconstruct security incidents.

At Ghana-India Kofi Annan Centre of Excellence in ICT, I scanned systems with Nessus and OpenVAS, analyzed vulnerabilities, and tracked remediation. I also annotated and validated AI training datasets at Invisible Technologies.
