I will build a custom API or backend in csharp dotnet with postgresql

Need a reliable, scalable backend for your web or mobile app?

I'm a C# .NET developer with experience building robust APIs and backend systems that power websites, mobile apps, and business tools. Whether you're launching a startup, need a custom API, or want to fix an existing backend, I'm here to help.

What I'll build for you:

• RESTful APIs with clean architecture
• Database design and integration (PostgreSQL, SQL Server)
• User authentication (JWT, Identity)
• Third-party integrations (payments, email, etc.)
• Scalable, production-ready code

Why work with me?

•  Full-stack perspective: I also work with React and Angular, so I understand how your frontend will consume the API
•  Clean code advocate: I follow best practices so your project is maintainable
•  Performance focused: I optimize queries and responses for speed

My stack:

• C# / .NET 6/7/8
• PostgreSQL / SQL Server
• Entity Framework Core / Dapper
• JWT / Identity
• REST / WebSockets
