I will build a document data extraction API with asp net core and sql server
Abhishek
About this gig
Need invoice or PDF data to flow into your own software? I build a clean ASP.NET Core Web API that accepts a PDF, extracts the key fields, checks the maths, and returns structured JSON your app can use. Higher packages store the results in SQL Server so you can save, list and search them.
What you get: a working API project with source code, upload and retrieval endpoints, validation that flags totals that do not add up instead of guessing, and clear setup notes.
About me: I am a .NET developer with 3+ years of professional experience building enterprise and government applications in C#, ASP.NET Core, Entity Framework Core and SQL Server. My document-extraction work so far is in sample projects, not client work, and extraction is rule-based per invoice layout (no AI model). Send me sample invoices first and I will tell you honestly if your layouts are a good fit.
Not included: scanned images (OCR), hosting, or AI model setup. Message me before ordering for anything beyond the package scope.

Software developer with 3+ years of professional experience building enterprise and government applications in C#, ASP.NET Core, Web API, Entity Framework Core and SQL Server. I help small businesses and dev teams turn invoices, receipts and PDFs into clean structured data (JSON, Excel or CSV) and connect it to their own .NET apps and databases through a simple API. Expect clear scope before I start, honest communication and well-organised code. My AI document-extraction work is built as sample/demo projects, and I will always say exactly what I have and have not built.
FAQ
Does it read scanned images or photos of invoices?
Not in this gig. The API reads text-based PDFs. Scanned images need an extra OCR step, so message me first and I will quote it as a custom offer.
Which invoice layouts does it support?
Basic is built for one layout you send me, Premium for up to three. Extraction is rule-based per layout, so please send real sample invoices before ordering.
Do I get the source code, and can I host it myself?
Yes, every package includes the full source code. I do not host it for you, but the setup notes explain how to run it on your own server or machine.
Can you work with my existing database or system?
Standard and Premium store results in SQL Server using Entity Framework Core. If you use another database or need to plug into existing code, message me before ordering.
