Hi, my name is

Ian Njoroge Mathu.

Securing Infrastructure & Automating Networks.

I am a Computer Networks & Cybersecurity specialist. I build secure, scalable environments, automate incident response, and engineer low-level systems from the kernel to the cloud.

About Me

A fresh graduate with a degree from Strathmore University, I enjoy building digital infrastructure with confidentiality, integrity and availability as my guiding principles.

Recently, I completed an internship at the Royal Media Services headquarters. Beyond day-to-day firewall, VLAN, and server management, I thrive on taking initiative. During my time there, I proposed and successfully implemented a project to secure LAN access using existing company Active Directory credentials, bridging the gap between networking hardware and identity management.

Whether I am configuring complex routing protocols, finetuning Large Language Models (LLMs) for threat detection, or writing Ansible playbooks to automate server deployments, my focus is always on precision and scalability.

I am always open to new opportunities to learn, collaborate, and contribute to projects that make a meaningful impact in the field of cybersecurity and network automation.
