About this Gig

Still copying data from invoices, receipts or forms by hand?


I build AI pipelines that read your documents and return clean, structured data (JSON, CSV or Excel), even from scans and photos.


How it works:

- OCR reads the text, including from low-quality scans

- An LLM extracts the exact fields you need: totals, dates, line items, names

- Validation rules flag missing or suspicious values for review


Why work with me:

- Top 6 of 269 teams, ICPR 2026, OCR on low-resolution images

- Top 1 of 1,060 teams, Zalo AI Challenge 2025 (computer vision)

- I build LLM and RAG systems, so the extraction step is accurate and explainable


What I can process:

- Invoices, receipts, purchase orders

- Forms, contracts, ID-style documents (with your consent)

- Mixed batches of PDFs and images


You receive the extraction script or API, a sample output on your files, and documentation.


Send me 3 to 5 sample documents and the fields you need. I will confirm accuracy on your real data before you order.
