Confidential, Raleigh, NC

Integration Solution Architect - Healthcare

Responsibilities:

• Designed and implemented BizTalk based architectures for various solutions. (Hub, IR, Prescriptions, etc.) using BizTalk 2013 through BizTalk 2016 and associated ESB Toolkit version. Many solutions have extreme low latency requirements which require performance tuning BizTalk layer, the underlying SQL Server layer and virtualization layer (including SAN and networking layers).
• Led project as a part of the company’s cloud migration strategy to determine which BizTalk-based workloads can be moved to Azure IaaS. This project involved performance testing existing solutions in Azure IaaS using different configurations. Tested different Azure networking options (accelerated network and RDMA), disk configuration (Unmanaged HDD, Managed HDD/SSD Premium, Managed Ultra SSD). Compared cost of larger drives vs striping smaller drives to achieve IOPS requirements. Tested SQL Server High Availability options including Availability Groups and Failover clusters in Azure.
• Led project to determine tools selection for Infrastructure as Code (IaC) as a part of the company’s cloud migration strategy. Build framework to automate the deployment of various workloads to Azure using ARM template (initially) and Terraform and Azure Desired State Configuration (DSC). Build Terraform modules to encapsulate functional and limit possible configuration errors of environments created with the framework. Framework also allowed separated management of non-application portions of the deployed solutions like networking and Identity management. Wrote PowerShell DSC scripts to deploy required application packages on the IaaS resources create with Terraform.
• Led project to prototype re-architecting several small workloads to Azure Service Fabric using Stateful and Stateless Reliable services programming model. This including using Git or Azure Repos for source control management and Terraform to build infrastructure using IaC and Azure DevOps pipelines.
• Led project to prototype re-architecting several small workloads to Logic Apps and Azure Functions programming model. This including using Git or Azure Repos for source control management and Terraform to build infrastructure using IaC and Azure DevOps pipelines.
