I will build rest apis with dot net core sql server or postgresql


About this gig
Need a secure, scalable backend API built with enterprise-grade .NET technology?
I build production-ready REST APIs using ASP.NET Core(8, 9) with SQL Server or PostgreSQL clean architecture, proper security, and full documentation so your frontend, mobile app, or third-party service connects without issues.
WHAT YOU GET
- RESTful API with clean controller/service structure
- Database design with Entity Framework Core + Migrations
- SQL Server or PostgreSQL your choice
- JWT-based authentication & authorization
- Role-based access control (RBAC)
- Input validation & structured error handling
- Repository pattern / Clean Architecture
- Swagger documentation included
WHY THIS IS DIFFERENT
3+ years of production .NET Core experience across fintech and telecom platforms. I've built systems handling real enterprise load not tutorial CRUD apps. You get architecture that a senior engineer would be comfortable maintaining.
I CAN ALSO HANDLE
- Extending or refactoring existing .NET Core projects
- Migrating from .NET Framework to .NET Core/8 or 9
- Third-party API integration

FAQ
Which .NET version do you use?
I work with .NET Core 7, 8, and 9. I recommend .NET 8 (LTS) for new projects unless you have an existing version requirement.
SQL Server or PostgreSQL — which should I choose?
SQL Server is better if you're on a Windows/Azure stack or need enterprise support. PostgreSQL is better for cost, open-source deployments, and AWS/Linux environments. Message me if unsure — I'll advise based on your setup.
Can you work with my existing .NET project?
Yes. Share the codebase via GitHub or ZIP before ordering so I can assess complexity and confirm the right package.
Do you follow clean architecture or just MVC?
Standard and Premium packages follow a layered clean architecture — Controllers, Services, Repositories, and Domain models separated. Basic package uses standard MVC structure.
Can you deploy the API as well?
Deployment is not included in this gig but I offer a separate AWS / Docker deployment gig. I can bundle both at a custom price — message me.
