Kingsley Obichere

Built and operated production cloud platforms on AWS/Azure using Terraform and Kubernetes (EKS/AKS). Migrated 200+ on-prem servers to a hybrid estate and applied FinOps controls to reduce annual spend by $1.2M+. Designed multi-AZ node pools and autoscaling (HPA/cluster autoscaler) to sustain 99.99% availability for multi-region EKS/AKS processing millions of daily healthcare transactions. Reduced environment provisioning time from ~3 days to under 1 hour by creating 70+ reusable Terraform modules with remote state and PR-driven plan/apply pipelines. Increased deployment frequency from biweekly to 4+ releases per day for 55+ applications using GitOps CI/CD (GitHub Actions, Azure DevOps, ArgoCD), quality gates (SonarQube), and automated rollbacks. Improved MTTR by 75% (4 hours to under 1 hour) through an observability stack with SLO-based alerting and runbooks. Automated vulnerability scanning and patch workflows to raise patch SLA compliance to 99% and reduce manual remediation effort b

Codified AWS/Azure infrastructure with Terraform and ARM templates, reducing provisioning time by ~95% (3 days to under 4 hours). Improved reliability by migrating 50+ legacy monoliths to containerized microservices on AKS using Docker and Helm. Reduced deployment windows by 90% (5 hours to 30 minutes) by consolidating automation in Jenkins and Azure Pipelines. Architected enterprise marketing platform infrastructure to absorb a 10x seasonal traffic spike with zero customer-facing downtime. Designed cross-region disaster recovery with Azure Site Recovery to reduce RTO from 6 hours to 30 minutes and supported SOC 2 Type II certification via access hardening (Azure Bastion, managed identities, Key Vault, NSGs, RBAC) and centralized logging. Built a centralized Azure Data Lake with automated ingestion pipelines to support predictive modeling for 15+ business units.

Led data center-to-cloud modernization for 120+ workloads, reducing physical infrastructure dependency by 80%. Containerized Java and .NET applications with Docker and Kubernetes and standardized Helm charts across dev/staging/prod, cutting deployment errors by 50%. Achieved 99% audit compliance across 450+ VMs by automating patching with Azure Automation and PowerShell. Delivered multi-tenant GKE clusters for 12 engineering teams using Terraform with namespace isolation and RBAC. Reduced incident escalations by 75% and sustained 99.9% availability for 150+ remote users using secure Azure networking (VNet, NSG, UDR, VPN Gateway) and Azure Monitor alerting.
