Samiur Rahman is a Cloud Engineer focused on Microsoft technologies, with a background in cloud network engineering. He works across the architecture, governance, identity, and reliability of enterprise-scale Azure environments, including the platform engineering behind production AI workloads.
He is currently a Cloud DevOps Engineer at LEO Pharma, one of the senior engineers responsible for the company’s Azure platform: 200+ subscriptions and a 15,000-user tenant, governed end to end with Terraform. The role covers platform architecture (App Services, high-performance VMs, network gateways), enterprise identity on Microsoft Entra ID, CI/CD in Azure DevOps, and reliability engineering for the production fleet. He is also responsible for the lifecycle of the company’s generative AI models in Azure AI Foundry — principally Anthropic Claude and OpenAI GPT — together with the secure AI gateways that connect Foundry to internal systems.
He acts as the senior escalation point for incidents across the Microsoft ecosystem, leads resolution of critical network incidents, and advises Cyber Security leadership on Azure and Intune. In 2025 he delivered around DKK 570,000 (€76,000) in annualised savings through cloud FinOps. He is part of a cross-disciplinary team of cloud, data engineering, data science, and AI, reporting to the Head of AI & Cloud Data Services in Copenhagen.
He was previously a Senior Cloud Network Engineer at Microsoft (Azure CSS), handling incidents of global criticality daily with a constant caseload of 20 to 30 cases under strict SLAs. The work meant resolving networking problems that customers’ own engineers could not, across ExpressRoute, private peering, DNS, AKS, and most of the Azure networking stack. Customers included Fortune 50 enterprises and government organisations such as the Government of the United Kingdom, the British Transport Police, and the Government of South Australia. Earlier roles were held at BNP Paribas in Kraków and Honeywell in Katowice. He holds 36+ certifications from Microsoft, Cisco, and Palo Alto Networks.
Samiur is also a trainee pilot, having completed the EASA Private Pilot Licence ground school at ATO Avioner in Warsaw with a rating of 94%. He is currently in the practical phase of the course.
