Project details
I build and improve REST APIs and third-party integrations in .NET applications. This project is a good fit if you need a new endpoint, external service connection, webhook flow, authentication setup, or help fixing an unstable integration. I work on request and response handling, data mapping, error handling, and backend logic so the integration works in a practical and maintainable way. Whether you need a small API task or a larger integration flow, I can help you build it properly.

About Muhammad Usama
Full Stack .NET Developer | C#, ASP.NET Core, React, Azure
Sargodha, Pakistan - 7:39 am local time
I am a full-stack .NET developer with 6+ years of experience working with C#, ASP.NET Core, .NET Core, .NET Framework, ASP.NET MVC, SQL Server, JavaScript, React, Next.js, and Microsoft Azure.
I work on both new development and existing systems. That includes bug fixing, feature development, API integration, performance improvement, database work, cloud deployment, and long-term product support.
I have built and maintained admin portals, dashboards, reporting modules, SaaS applications, and business systems across multiple domains, including fintech, hotel, payments, transportation, logistics, and healthcare.
I am comfortable with both modern .NET applications and legacy systems. I can quickly understand an existing codebase, fix issues carefully, and add new features without breaking what already works.
My experience includes:
Backend development with C#, ASP.NET Core, .NET MVC, Web API
Third-party integrations and API-based systems
REST, GraphQL, gRPC, and service-based communication
SQL Server, MongoDB, Oracle, and other business databases
React, Next.js, JavaScript, jQuery, Bootstrap, and Material UI
Microsoft Azure deployment, maintenance, and cloud support
AI integrations using modern tools and APIs such as GPT, Claude, and Gemini
Clients hire me when they need a developer who can take ownership, communicate clearly, solve real business problems, and deliver production-ready work.
Whether you need a full-stack .NET developer, backend API engineer, integration specialist, or long-term support for an existing application, I am ready to help.
