About
I spent two years running HR at a home health agency. About half the software we used was too generic for healthcare, and the rest was priced for hospital systems, so I started writing our own.
Most of what I build comes with a way to check it. The hockey model is graded against 735 real signings, and I publish where it misses. The PDF editor has a test harness that scores replaced text against the scanned original. The light controller picks its color correction model by cross validation.
CredentialHQ is my main project. I keep working on the hockey model because I want to do this for an NHL team. EasyFax runs at the agency every day, and PDF for Free is a public download.
