I will develop asp net core web API rest API with c sharp and sql server
Sakib Hossain
About this gig
Need a clean and reliable API for your web or mobile application?
I can build ASP NET Core Web APIs that are easy to integrate, maintain, and extend as your application grows.
I can help with:
- ASP NET Core Web API and REST API
- CRUD API development
- Entity Framework Core and LINQ
- SQL Server database integration
- JWT authentication and authorization
- Role and claims based access
- FluentValidation and business logic
- Repository and service implementation
- Third party API integration
- Existing API improvements
I have practical experience building APIs for real business applications, so I pay attention to more than just making an endpoint work. I focus on clear structure, validation, database handling, security, and maintainable code.
If you already have a frontend or an existing .NET project, I can work with that as well.
Send me your requirements before ordering if you are unsure which package fits your project.

Hey, I'm Sakib — a full stack developer working with ASP.NET Core, C#, Angular, and SQL Server for 3+ years now.
I've mostly worked on real business systems — ERP, POS, inventory, and e-commerce platforms — so I've dealt with messy legacy code, slow queries, and clients who needed fixes fast.
I handle APIs, EF Core/LINQ, database design, auth, and performance issues. I ask questions when something's unclear and keep you updated instead of disappearing.
Got a bug or a project? Message me, let's talk it through.

FAQ
Can you work with my existing ASP NET Core project?
Yes. I can add new API endpoints or improve existing functionality while following your current project structure.
Can you add JWT authentication?
Yes. I can implement JWT authentication, authorization, roles, claims, and protected API endpoints.
Do you work with Entity Framework Core and SQL Server?
Yes. I can handle EF Core entities, relationships, LINQ queries, migrations, CRUD operations, and SQL Server integration.
Can you connect the API with an Angular frontend?
Yes. I also work with Angular, so I can help with frontend and API integration when required.
Can you integrate a third party API?
Yes. I can integrate external REST APIs and handle requests, responses, authentication, and data mapping. Please message me first with the API details.
What if I need more endpoints than the package includes?
Send me your requirements and I can provide a custom offer based on the number of endpoints and complexity.
