Hello John Dim.
I propose to develop an executable file for your parser, built in Rust. I have had experience building web servers and CLIs.
I can break the scope into three components:
1. Parsing of text, review inputs and outputs
2. Add pdf, doc, csv, xls, webpage document support
3. Storing data in database
I require details on how you are storing this data and what you require with regards to how the tool should be accessible through a web service.
If you could provide test data it would greatly accelerate the iteration testing.
I expect the job to take ~10 hours work spread out over ~7days.
