I’ve spent more than 13 years building C# and .NET applications, with the past several years focused on Azure PaaS architecture and delivery. My recent work has centered on choosing practical Azure services, improving reliability, and helping large teams turn business requirements into systems they can operate confidently. In my current role, I lead delivery for .NET Core services running on Azure App Service and Azure Functions. I redesigned asynchronous processing with Azure Service Bus, Blob Storage, and Azure SQL to make high-volume document and transaction workflows more resilient without changing customer-facing APIs. I also introduced reusable Azure DevOps pipelines with gated pull requests, automated unit, integration, and functional tests, and consistent Git branching practices. For production support, I built Application Insights dashboards, distributed tracing, alerting, and runbooks that gave the team a clearer path from an alert to the underlying bottleneck. Security and communication are part of how I approach architecture. I’ve implemented Key Vault, managed identities, Azure AD role assignments, and environment-specific access controls, while explaining the tradeoffs to product, operations, security, and executive stakeholders. Earlier roles strengthened my hands-on experience with MVC, REST APIs, Entity Framework, SQL tuning, Angular, and integrations using SendGrid and Service Bus. I would bring that combination of implementation depth, platform judgment, and steady ownership to Northstar CloudWorks. I’d welcome the opportunity to discuss how my experience designing and supporting Azure-based .NET platforms could help your team deliver reliable services and improve the development process. Thank you for your consideration. Sincerely, Click to edit Draw your signature below Clear Generate Signature Save X Joon Miller
