What I'm looking for

I'm looking to build scalable, secure enterprise backend systems where I can modernize .NET platforms, solve performance challenges, strengthen reliability, and collaborate through Agile delivery.

At Programmers.ai, I build and maintain backend services and REST APIs for enterprise field-service and ERP-integrated platforms spanning legacy .NET Framework services and a modern .NET 9 dispatch portal.

I led a legacy ASP.NET MVC/.NET 6 modernization to .NET 9 with clean architecture, supporting a React 18 and TypeScript SPA. I improved SQL-backed API performance by more than 50%, including reducing a critical multi-million-row production query from about 10 seconds to under 1 second.

I investigate production issues across APIs, business logic, Entity Framework, and SQL Server, with a focus on data integrity, concurrency, transaction handling, and reliable distributed workflows.

Previously at Dreamsoft4U, I developed C#, ASP.NET MVC, and SQL Server applications, designing database schemas and reusable server-side components. I also deliver secure, tested software through Auth0-based security, Azure DevOps CI/CD, automated testing, code reviews, and Agile Scrum collaboration.
