KenyaSenior Platform and Infrastructure Engineer at Polariks (Bosman Van Zaal)
About
I've delivered Kubernetes platforms at Polariks supporting 1,000+ connected IoT devices at 99.9% uptime, using AWS EKS, GCP GKE, Terraform, Helm, Docker, and GitHub Actions.
Across Digital Sacco, Enaton Tech, and SoulKode, I've operated regulated on-premise Linux infrastructure, built isolated container environments, and automated deployments with Ansible, GitLab CI, Docker Compose, and Bash. My work has reduced mean time to resolution by 30%, accelerated delivery cycles by 60%, and supported 5x traffic growth without additional infrastructure cost.
I'm based in Nairobi and communicate infrastructure decisions clearly through runbooks, configuration guides, and practical documentation for engineering, operations, and non-technical stakeholders.
