I build, modernize, maintain, and scale business-critical web applications and software using .NET, C#, ASP.NET Core, React, Angular, AWS, and SQL Server.
My work covers full-stack and frontend development, with a strong focus on reliable, scalable, and maintainable applications. I work across backend, APIs, databases, cloud infrastructure, and modern frontend interfaces, so you can have one developer who understands the complete application.
Whether you need a new full-stack web application, a React or Angular frontend, legacy .NET modernization, API integrations, Amazon Seller APIs, a cross-platform .NET MAUI application, AWS Cognito authentication, or SQL Server optimization, I can help take the project from requirements to production.

I prefer understanding the existing system and business requirements before recommending a technical solution.
For full-stack projects, I can work across the application—from frontend UI with React or Angular to .NET/ASP.NET Core APIs, business logic, authentication, databases, and cloud integrations.
For legacy applications, the goal is not to rewrite everything simply because newer technology exists. The goal is to modernize safely, improve maintainability, and reduce technical risk.
If you have a new full-stack application, a React or Angular frontend, an existing .NET application that needs modernization, an API integration, an Amazon Seller system, or a database/application that needs performance improvements, send me the details and I’ll help identify the right approach.
