About this gig

Many businesses still process documents manually, such as invoices, receipts, reports, and contracts. This is time-consuming and often leads to errors.


I build AI-powered document processing systems that automatically extract structured data from documents and images using modern Large Language Models. These systems convert unstructured documents into clean JSON or structured datasets that can be used in accounting tools, databases, or internal workflows.


I have experience developing AI pipelines that process documents using vision-capable models and expose the results through reliable APIs.


What I can build for you:


AI systems to extract data from invoices, receipts, and PDFs

Document processing pipelines for business workflows

AI-powered document classification and automation

Custom APIs for document data extraction


Example extracted fields:


Invoice number

Vendor name

Date and currency

Total amount

Line items


Technologies: Python, FastAPI, LLMs, LangChain, DSPy, Pinecone, Docker.


The solution can be delivered as an API, automation tool, or integrated into your existing system.


Please contact me before ordering to discuss your requirements.
