I will build an ai system to extract data from your pdfs and documents
About this gig
Manually copying data from invoices, forms, receipts, or scanned documents is slow and error-prone. I build AI-powered extraction systems that read your documents and turn them into clean, structured data, automatically.
I use large language model APIs combined with document parsing to pull specific fields from PDFs, scanned images, and forms, then output results as JSON, CSV, or directly into your database. This approach understands context, so it handles varying layouts, handwriting, or inconsistent formatting better than basic OCR.
Where this helps: invoice/receipt line items, applicant data from resumes, structured data from contracts or reports, and feeding clean data into your existing systems.
I'm a senior full-stack engineer with production experience building a document management platform for banking industry. I build extraction pipelines with validation and error handling, not just a single API call.
How it works: send 3-5 sample documents, I build and test extraction logic against them, then deliver the working system with documentation.
Note: accuracy depends on document quality. I'll flag any documents too degraded to extract reliably before starting.

FAQ
What file formats do you support?
PDF, scanned images (JPG/PNG), and most standard document formats. For handwritten documents, accuracy may vary and I will let you know upfront if a sample looks difficult.
What AI technology do you use?
I use leading large language model APIs (such as those from Anthropic and OpenAI) combined with document parsing tools, chosen based on what fits your accuracy and budget needs.
Can you integrate this into my existing system?
Yes, this is included in the Premium package. For Basic and Standard, I deliver the extraction logic and output format, and integration can be discussed as a custom offer.
My documents have inconsistent layouts, can you still handle it?
Often yes, since I use LLM-based extraction rather than rigid template matching, which handles layout variation better than traditional OCR. Send samples and I will confirm before we start.
Is my data kept confidential?
Yes. I do not store or reuse your documents beyond the scope of the project. Let me know if you need an NDA before sharing sensitive files.
