Cloud and System Automation

Category : Networks, telecom and cloud

Cloud and DevOps engineer with a passion for turning complex infrastructure challenges into elegant, automated solutions.
Over my career in the ICT industry, I've worked across the full infrastructure stack — from physical data centres to multi-cloud environments on Azure and AWS. I specialise in bridging the gap between development and operations: building the pipelines, platforms, and practices that let teams ship with confidence.

My toolkit includes:
• Azure & AWS architecture (CAF, hybrid networking, migrations)
• Infrastructure as Code — Bicep, Terraform
• CI/CD automation and DevOps workflows
• Configuration as Code - Ansible automation for Linux and Windows
• Windows & Linux administration and scripting

I hold certifications as an AWS Solutions Architect, Microsoft Azure Solutions Architect, and DevOps Expert, RHCE — and I'm always learning.
If you're working on something interesting in the cloud or DevOps space, I'd love to hear about it.
