About this Gig
Still paying someone to type data off invoices, receipts, IDs or forms by hand?
I build OCR and Document AI systems that read your documents and return clean, structured data straight into your spreadsheet, database or app.
WHAT I EXTRACT
- Invoices and receipts: line items, totals, dates, tax, supplier details
- ID and KYC documents: passports, licences, national IDs
- Contracts and forms: clauses, fields, signatures, checkboxes
- Handwritten and scanned documents, including poor quality scans
- Tables, even when they run across multiple pages
Every pipeline includes validation rules that catch errors before they reach you, structured JSON, CSV or Excel output, and an accuracy report so you know how it performs on your documents, not on a demo.
STACK: Python, PaddleOCR, Tesseract, AWS Textract, Google Document AI, Azure Document Intelligence, GPT-4 Vision.
NOT SURE IT WILL WORK ON YOUR DOCUMENTS?
Start with the Proof of Concept. Send 3-5 real documents and I will show extraction running on YOUR data, with an accuracy report, before you commit to a full build.
Message me with 2-3 samples and the fields you need, and I will tell you honestly what is possible.

FAQ
Will this work on my specific documents?
That is exactly what the Proof of Concept package is for. Send 3-5 of your real documents and I will run extraction on them and show you the results with an accuracy report before you commit to anything larger. If your documents turn out to be a poor fit, you will find out for a small amount rather
What accuracy can I expect?
It depends on your documents, and anyone who quotes you a number before seeing them is guessing. Clean digital PDFs with consistent layouts typically reach very high accuracy. Poor scans, handwriting and highly variable layouts are harder. This is why every package includes an accuracy report measur
Do I get the source code and a working API?
Yes, from the Standard package up. You get full source code, and Premium includes an API plus deployment to your own server, containerised with Docker, and documentation so your team can maintain it without me.
My documents are confidential. Is my data safe?
Yes, and I will be specific about it. I only need sample documents, and you can redact sensitive values before sending. If your documents cannot be processed by a third-party service at all, I can build the whole pipeline with self-hosted open-source OCR so nothing leaves your own infrastructure. Te
Can you handle handwritten text or low-quality scans?
Often yes, but honestly it varies more than printed text does. Handwriting, faded scans, skewed photos and low-resolution faxes all reduce accuracy, and the extent depends on your specific documents. Pre-processing helps a lot. Send samples of your worst-case documents in the Proof of Concept and yo
What output format do I get?
Whatever fits your workflow: structured JSON, CSV, Excel, or written directly into your database or app via API. Tell me where the data needs to end up and I will deliver it in that shape rather than handing you a file to convert yourself.
