As an experienced Microsoft Certified Azure Architect Expert, I am well-suited to this project. I have passed the AZ-305 and AZ-104 exams, which demonstrate my proficiency in Azure cloud management, administration, and solutions architecture. With my command over automation skills like PowerShell, Python, batch, and bash scripting, I can efficiently automate your R script for scheduled execution on Cloud - when even you're not using your local PC.
Moreover, leveraging my expertise in hybrid and cloud solutions, it would be a seamless process to ensure your R script's interaction with SharePoint is successful. My advanced experience across IT operations including networking, virtualization, identity, security etc., ensures that data transfer or transformation between Azure and SharePoint will be rapidly handled complying high level of security.
My skills extend beyond Azure management; I'm also well-acquainted with AWS services like EC2, EKS, ECR - many more intriguing services that reside in the AWS ecosystem. So if you decide to future-proof this project by incorporating any additional cloud service providers/platforms into your environment (whether now or in future), I'll be able to provide equal level of expertise this other environment may require.
