About

I’m a cybersecurity student at AltSchool Africa, currently building hands-on skills in network and cloud security. I’ve worked on simulations using tools like Wireshark and Cisco Packet Tracer, and I’m particularly interested in threat detection, IAM, and cloud security fundamentals. I’m open to opportunities that allow me to grow and contribute in cybersecurity-related roles.

Summary

Designed and implemented a secure Wide Area Network (WAN) connection between two simulated branch offices — Ghana and Cape Verde — using Cisco Packet Tracer. The project focused on network segmentation, CIDR-based IP addressing, access control lists (ACLs), and traffic filtering to ensure only ICMP and HTTP services were permitted. Successfully documented network configurations, verified security policies through testing, and produced a working simulation model as part of AltSchool’s cybersecurity curriculum.
