What I'm looking for

I seek a senior DevSecOps/cloud platform role where I can lead secure, automated CI/CD and infrastructure initiatives, mentor teams, and drive reliability and compliance.

I am a versatile DevSecOps engineer with seven years of experience automating and managing large-scale cloud and hybrid deployments, with a strong programming background in Python and Go. I specialize in container technologies (Docker, Kubernetes), infrastructure-as-code, and building resilient, secure production platforms.

I have led PCI DSS v4 certification for M‑Pesa GlobalPay, migrated on-prem workloads to cloud environments, and implemented multi-cluster observability using OpenTelemetry, Thanos, Grafana Tempo and ELK, ensuring 99.9% uptime across critical services. I design and operate CI/CD pipelines with Jenkins, GitLab CI, Tekton, Argo CD and Flux, and manage infrastructure with Terraform, CloudFormation, Crossplane and Ansible.

I bring hands-on experience with service mesh (Istio), extensive monitoring and incident resolution, and automation that reduced release time and downtime across organizations. I collaborate across teams to deliver secure, scalable platforms that balance reliability, performance and compliance.
