I’m a Cloud Infrastructure Engineer with 2+ years of experience delivering secure, scalable, and highly available solutions across AWS and Azure. I specialize in infrastructure as code, cloud migration, Kubernetes, observability, and cost optimization, with a strong execution mindset and a “continuous learning” approach to cloud innovation.

At Equity Bank Kenya Limited, I led security architecture and implementation of app services, virtual machines, storage accounts, and key vault security using the Well-Architected Framework—disabling public access and reducing our attack surface by over 30%. I also improved incident response processes, reducing MTTR by 35% through proactive monitoring, root cause analysis, and automated remediation in Azure Kubernetes Service (AKS).

I built reusable Terraform modules for AKS cluster upgrades and PCI/DSS environments, streamlining resource deployment by more than 90%. I deployed Dynatrace and Datadog agents across Azure AKS, Azure Virtual Machines/VMSS, and AWS EC2/EKS to enhance observability by 30%, while Azure Resource Graph tagging and governance initiatives removed more than 95% of idle resources and reduced costs by 20% as at November 2025.

I partner closely with Security Architects, SOC engineers, and Threat Intelligence Analysts to remediate vulnerabilities—using Azure policies to scan for compliance and deny future creation of risky workloads—reducing our threat landscape by over 70%. Earlier, at E&M Technology House Ltd, I led cloud infrastructure design and SRE monitoring, improving service availability by 40% through AWS migrations, achieving 99.99% availability via EC2 with Availability Zones, and delivering CI/CD pipelines with Azure DevOps, Code Pipeline, and Terraform.
