Vijay Kanna
About this gig
Need a backend for your web app, mobile app or business workflow? I will build clearly scoped REST APIs using C#, ASP.NET Core and SQL Server or PostgreSQL.
I am Vijay Kanna, a full-stack developer with 9+ years of experience in enterprise integrations, fintech systems and my own property-management SaaS. I am also an Envato author with two published CodeCanyon products.
Services include REST endpoints, database CRUD, validation, existing authentication integration and third-party API connections. Delivery includes the agreed source code, verification of endpoint behavior and setup/API documentation.
Basic covers up to 2 simple endpoints in an existing .NET app. Standard covers up to 5 endpoints for one SQL entity. Premium covers up to 8 endpoints plus one agreed external integration and existing auth setup. One endpoint means one HTTP method and route.
Message me before ordering to agree the data model, business rules and integration scope. Frontend screens, full identity platforms, payment certification, hosting, paid services and large migrations are quoted separately. Revisions cover the agreed scope.

FAQ
What counts as an endpoint?
One endpoint is one HTTP method and route, such as GET /items. We agree the routes, data model and business rules before ordering. Complex workflows require a custom quote.
Is a frontend or hosting included?
These packages cover backend API work. Frontend screens, hosting, paid third-party services and ongoing maintenance are quoted separately. Source code and setup/API documentation are included.
Can you integrate authentication or external APIs?
Yes. Premium includes one agreed external API integration and connecting an existing authentication setup. A new identity platform, complex provider flows or additional integrations need a custom offer.
