I will develop asp dotnet core web API with jwt auth and sql server backend


About this gig
Are you looking for a professional, production-ready REST API built with ASP.NET Core C#?
I am a Full-Stack .NET Developer & ERP Specialist with 5+ years of experience delivering enterprise-grade web APIs for startups, SMEs, and large businesses. I build APIs that are clean, secure, scalable, and fully documented so your team can integrate and ship faster.
--- What you get ---
ASP.NET Core Web API built with C# best practices
SQL Server database design & Entity Framework Core
JWT / OAuth2 authentication & role-based authorization
Full CRUD operations with proper HTTP status codes
Swagger / OpenAPI documentation (interactive UI)
Repository pattern & clean architecture
Error handling, logging & input validation
Tested endpoints & Postman collection included
--- Why choose me? ---
I don't just write code I think like a business owner. Every API I build is designed for real-world use: maintainable, secure, and ready to scale.
ERP background means I understand complex data relationships, multi-module integrations, and business workflow logic that generic developers miss.
You'll get clean, commented code you can actually maintain after delivery.

FAQ
Can you integrate the API with my existing database?
Yes. If you already have a SQL Server database, I can reverse-engineer the schema and build the API on top of it. Share your schema or an ERD and I'll confirm feasibility before you order.
What if I need more endpoints than the package allows?
I offer custom gig extras for additional endpoints. Message me with your full requirements and I'll create a custom offer that fits your exact scope and budget.
Do you provide source code?
Yes. You receive full, clean, commented source code via a GitHub repo or ZIP file. All packages include 100% ownership of the code with no hidden licensing.
Can you work with an existing ASP.NET project?
Absolutely. Send me the project and I'll review it first. I handle legacy .NET Framework migrations, bug fixes, refactoring, and adding new modules to existing systems.
