Mostafa N.

Platform Engineering Tech Lead and former DevOps Solution Architect with nearly 9 years of hands-on cloud experience across AWS, Azure, and GCP. I currently lead the platform team behind a multi-tenant Azure landing-zone platform that gives Vodafone markets across Europe self-service infrastructure. I hold five AWS certifications, including Solutions Architect Professional and DevOps Engineer Professional. Key Strengths & Skills: Multi-Tenant Platform Design: Azure landing zones with hub-and-spoke networking, Azure Firewall, private DNS, and private endpoints; multi-tenant EKS and AKS for shared workloads. Infrastructure as Code: Terraform and Terragrunt at scale, including multi-stage chained pipelines that provision networking, clusters, and tenant environments end to end. Kubernetes & GitOps: AKS and EKS, ArgoCD, Cilium, and self-hosted GitHub Actions runners (ARC). CI/CD: GitHub Actions with reusable composite actions, Azure DevOps, and AWS CodePipeline, including ADO-to-GitHub migrations. Cross-Cloud Identity: Workload identity federation between Azure, GCP, and AWS, removing long-lived credentials from pipelines and workloads. AWS Data & Serverless: Aurora PostgreSQL performance tuning, ElastiCache Redis-to-Valkey migration, Lambda, and Step Functions. Security & Compliance: PCI DSS, SOC 2, and HIPAA implementations; Defender for Cloud; customer-managed key encryption (including MongoDB Atlas). Observability & Cost: Datadog and Azure Log Analytics; cost reduction across firewall, compute, and log ingestion in multi-cloud environments. Automation & Tooling: Python (including FastAPI-based internal tools) for platform automation and integrations. I work best on platform builds, cloud migrations, and security or cost reviews where the infrastructure needs to be reliable, auditable, and easy for other teams to consume.
