I will build a secure rest API in net core
Jake Y
About this gig
Need a backend for your web or mobile app, or new features on an API you already have? I'll build it in ASP.NET Core, done properly.
I'm a senior software developer with 8+ years of commercial C#/.NET experience, building APIs and microservices for healthcare (including NHS trusts), energy and manufacturing.
What I can do:
- Build a new REST API from scratch
- Add endpoints or fix bugs in your existing ASP.NET Core API
- Connect to SQL Server or PostgreSQL with Entity Framework Core
- Add JWT authentication, validation and proper error handling
- Write unit tests and Swagger docs, and Dockerize the API
What I need from you:
- What the API should do, and a list of endpoints if you have one
- Your existing code, for fixes or add-ons
- Your database choice, or I'll recommend one
Please note:
- Endpoint limits are per package, and extra endpoints are available as an extra
- Frontend work isn't included
- You get the full source code with every order
Not sure which package fits? Message me before ordering and I'll take a look.
