About Me

Building Networks, Securing the Future

I am a dedicated and results-driven IT professional completing a Diploma in IT (Network Management) at IIE Rosebank College. My expertise spans enterprise networking, cybersecurity, infrastructure automation and cloud technologies.

I have hands-on experience designing and implementing network architecture, administering multi-platform environments across Windows Server and Linux Ubuntu, and developing automation solutions using Ansible and Terraform.

I am passionate about building systems that are secure by design, scalable by architecture, and reliable in production.

"My mission is to design and defend the digital infrastructure that modern organisations depend on — building networks that are fast, secure and built to last."
