Building reliable AI document workflows

About

I’m building and validating AI products around document workflows, structured data, and reliable automation. Right now I’m working on PDflow, a public beta focused on turning messy PDFs into more usable spreadsheets while making uncertain structure easier to review. I’m especially interested in product validation, document reconstruction, human-in-the-loop workflows, and how AI products move from “it works” to “people trust it enough to use repeatedly.”
