What you get with this Offer
I will build a clean, reliable C# / ASP.NET Core Web API or data integration that connects your systems and keeps your SQL Server data in sync.
What I can build:
- REST or GraphQL Web API endpoints in .NET Core with SQL Server (EF Core or stored procedures)
- Real-time webhook receivers with validation and automatic retry handling
- Integrations with third-party APIs: Shopify, CRMs, payment or marketing platforms
- Background / scheduled sync services and backfills for historical data
- Logging, error handling and short documentation
Why me: 4+ years as a .NET developer building REST and GraphQL integrations for e-commerce and CRM platforms, including real-time Shopify webhook endpoints and backfill services for orders, checkouts and discounts.
This offer covers one API or one integration of moderate size. Message me first with your requirements for a custom quote on bigger projects.
