Nigeria Inter-Bank Settlement Systems • Full-time

Jul 2026 - Present • 3 mos

Platform engineering for Nigeria's national interbank payments infrastructure. - Architected and built Zero Touch Deployment, an internal developer platform that onboards a service to dev, QA, cert and prod in a single automated run using GitHub, Tekton, Argo CD, Kustomize and Infisical. - Migrated the default delivery strategy from Kubernetes Deployments to Argo Rollouts with Istio canary traffic shifting, giving every service metrics-gated progressive delivery and near-instant rollback. - Built Argo Rollouts AnalysisTemplates that gate each canary step on live Prometheus and Istio error-rate and latency metrics, removing manual go/no-go decisions from production releases. - Embedded a shift-left DevSecOps gate in every CI/CD pipeline: SAST (Semgrep), secret detection (Gitleaks), container and dependency scanning (Trivy, OWASP Dependency-Check), blocking promotion on High/Critical findings. - Implemented software supply chain security with CycloneDX SBOM generation and Cosign image signing and attestation, with centralized vulnerability triage in DefectDojo and Dependency-Track. - Standardized secrets management with Infisical so no secret values reach source control, and defined naming conventions across pipelines, manifests and Argo CD Applications. Tools: Kubernetes, Tekton, Argo CD, Argo Rollouts, Istio, Prometheus, Kustomize, Infisical, Semgrep, Trivy, Cosign, Python
