Senior .NET Developer | ASP.NET Core | C# | Azure | Web API |SaaS | AI

Senior .NET Developer and .NET Core Engineer with 15+ years building ASP.NET, ASP.NET Core, C#, REST APIs, microservices, and high-volume backend systems on Microsoft Azure. I specialize in scalable .NET applications, SQL Server, Dapper, Entity Framework, Redis, background workers, and enterprise modernization. A RECENT BUILD I was the core developer of a bordereau management system that was failing with memory exhaustion because entire policy files of 100K+ records were loaded into memory. I built the replacement as event-driven microservices and worker services on Azure Kubernetes Service. Files are streamed from Azure Blob Storage, records are processed in batches through Redis and Azure Queue Storage, and Helm-based CI/CD handles deployment and autoscaling. I also built the Angular front end. It is in production and designed for files from roughly 100K to over 1M records. WHAT I BUILD - RESTful APIs and microservices with ASP.NET Core / .NET 8+ - Event-driven and queue-based processing (Azure Queue Storage, Redis, background workers) - Azure solutions: App Services, Functions, Blob Storage, Key Vault, AKS, Azure DevOps pipelines - Angular front ends with Entity Framework or Dapper on SQL Server - Third-party API integrations - Azure OpenAI / Semantic Kernel features added to a .NET backend when there is a real use for them FIXING EXISTING MODERN APPLICATIONS If your .NET Core / .NET 8 application is slow, unstable or failing in production, I find the actual cause, whether it's the C# code, a query, a stored procedure or the deployment, and make the smallest safe change instead of proposing a rewrite. LEGACY .NET I also work on older ASP.NET Web Forms, MVC and .NET Framework applications on IIS. I can fix them in place or move them to .NET 8+ step by step, without a big-bang rewrite. HOW I WORK I ask questions early when requirements are unclear, flag risks before they become incidents, and keep changes small and testable. I use AI coding tools to move faster, but I review and test everything myself. I'm open to hourly work, fixed-scope projects and long-term engagements.
