Aashima N.

.NET developer and C# developer for businesses whose systems cannot talk to the software they depend on. One integration I built alone now handles 30,000 order creations a month for a US title insurance company. I am Aashima, a .NET developer with 12+ years in enterprise Microsoft systems. As a C# developer I work on three kinds of problem: legacy .NET applications that have outgrown their design, systems that need to reach software they were never built to reach, and new products that have to be right the first time. I handle architecture, development, testing and deployment myself, so one person is accountable for the whole result. RECENT WORK AS A .NET DEVELOPER A US title insurance company ran residential closings on ResWare with a custom PHP application on top. They wanted to move to SoftPro. SoftPro is only reachable from .NET, so their PHP application had no way to talk to it. I built the .NET REST API layer between the two, end to end, on .NET Framework 4.8, AWS EC2 and SQL Server. It creates orders and runs automation through the SoftPro client SDK. It now handles 30,000 order creations a month. Running in production since October 2024, 1,958 hours so far, and still mine to maintain. BACKEND WORK AS A .NET DEVELOPER AND C# DEVELOPER .NET Framework and legacy .NET, including .NET Framework 4.8 ASP.NET Core, .NET 8 and .NET 9, C#, LINQ ASP.NET WebForms, ASP.NET MVC, Razor Pages, Web API, Minimal APIs Microservices, gRPC, GraphQL and SignalR Clean Architecture, CQRS, MediatR, Repository, Unit of Work, SOLID Performance tuning for production workloads DESKTOP AND WINDOWS WPF and MVVM, WinForms, WinUI 3, MAUI, Blazor Windows Services and background workers Windows COM interop, including undocumented APIs that change between OS versions Legacy upgrades: WCF migration, VB6 to .NET, .NET Framework to .NET 8 INTEGRATIONS AND SECURITY REST APIs, GraphQL, Swagger and OpenAPI SoftPro Select integration using the SoftPro SDK Power Automate, Microsoft Graph API, SharePoint, Office 365 Stripe, Twilio, SendGrid Windows Active Directory with NTLM and Kerberos single sign-on JWT, OAuth2, OpenID Connect, Microsoft Entra ID CLOUD AND DEVOPS, AS AN AZURE DEVELOPER Microsoft Azure: App Service, Functions, Azure SQL, Service Bus, API Management, Cosmos DB, Azure AD AWS EC2 Docker, Kubernetes CI/CD with Azure DevOps and GitHub Actions Azure Service Bus, RabbitMQ, Kafka, MassTransit, NServiceBus Serilog and Application Insights DATA Microsoft SQL Server, PostgreSQL, MySQL, MongoDB Entity Framework Core, Dapper, ADO.NET Stored procedures, query tuning Redis, Elasticsearch Power BI FRONTEND, AS A FULL STACK DEVELOPER React, Angular, TypeScript, JavaScript Bootstrap, Tailwind CSS, HTML5, CSS3 HOW I WORK I am a full stack developer as well as a .NET developer, so backend and front end come from the same person rather than two hires. For work outside my stack I bring in a colleague under my supervision: a React developer when the front end is large, a WordPress developer or PHP developer for CMS work, and an Azure developer for infrastructure. I stay the single point of contact. If you are modernizing an older .NET application, hiring a C# developer to connect a system that cannot reach the software it needs, or building something new on Microsoft technology, send me a short note about what you are working on. I will tell you how I would approach it and where the risks are before you commit.
