5. What's the story behind DocSpring?

   I used to work at a payroll company (Gusto). We had built a similar in-house tool for filling out tax forms. I then built the first version of DocSpring (formerly named FormAPI) while I was living in Thailand. I built it to automate the filling out of visa application and visa extension forms, but realized that it could also be used for tax forms, real estate contracts, and any other kind of fillable PDF form.

Qpdf is a great tool. One of my other favorites is RUPS [2], which really lets you dig into the structure of a PDF.
