About Oualid
I design the cloud foundations that move telcos, banks and large industrial groups onto AWS, Azure and GCP — and keep them there profitably.
In 13 years I've delivered enterprise landing zones, FinOps cost models and zero-disruption migrations for Orange, Qualtech, Worldline, MMA, BNP Paribas, and other companies.
My designs pass enterprise architecture review on the first submission — that has been the rule, not the exception.
➤ Where I create value
• Enterprise foundations — multi-account landing zones, hub-and-spoke networks, identity (Entra ID / IAM / Cloud Identity), governance, security baselines.
• FinOps & cost optimisation — cost models baked into the HLD, not bolted on after the bill arrives. Typical outcome: 20–30% infra cost reduction in year one.
• End-to-end migrations — HLD → LLD → Terraform IaC → cutover, with zero-disruption playbooks for mission-critical workloads.
• Data & GenAI-ready platforms — Databricks, Snowflake, Vertex AI, Bedrock, Azure AI Foundry. Architectures built today to carry GenAI workloads tomorrow.
➤ Multi-cloud by design AWS · Azure · GCP — certified and hands-on enterprise delivery on each. Hybrid networking (ExpressRoute, Direct Connect, Interconnect, VPN), Kubernetes (AKS, EKS, GKE), Terraform, GitLab CI/CD.
➤ Why clients keep calling me back I translate between business, finance and engineering. CFOs trust the cost model. Architects trust the design. Delivery teams trust the cutover plan. Nothing ships into rewrite.
➤ Currently Cloud Solution Architect @Orange Business — architecting CASA v2 across Public Cloud and VMware.
