Full-Stack Developer for Invoice Processing Tool

I'm looking for a skilled full-stack developer to build a program that takes a PDF containing multiple invoices as input(small POC). The tool should be able to separate the invoices and generate both a markdown file and a JSON file containing all the recognized content from each invoice.

Key Features:
- Utilize Python, React-JS, Microsoft tools and any relevant open-source tools.
- Implement logic to handle invoices with missing or unreadable information.

Ideal Skills:
- Proficiency in full-stack development.
- Experience with PDF processing and data extraction using OCR, other AI tools what ever you want.
- Strong knowledge of Python and React-JS.
- Familiarity with JSON and Markdown formatting.

Please note, specific details about the data to be extracted from each invoice, the structure of the output JSON and the handling of problematic invoices are yet to be determined. Your ability to provide flexible and adaptable solutions will be key to the success of this project.
this is a start of a bigger project.
so apply with fixed budget $50 for this small POC
start your bid with the word "Angry" otherwise, will be rejected
