JOHN ARNDT - README.TXT
=======================
Hi. This is my corner of the internet, dressed up as a
desktop from 1995. Everything on it is real and links out
to things that are live.
WHAT I DO
---------
I build and run small software products. Most of them
solve one specific, expensive problem for an
owner-operated business:
* finding the accounts worth calling today (Intakra)
* turning documents into structured data (Dokyumi,
W-2 Extractor, Pay Stub Parser)
* pricing a construction bid for a specific metro (Portravo)
A few are just for fun: RepDeck runs a workout clock,
Plastfri flags plastic while you shop.
HOW I WORK
----------
Small scope, shipped fast, then run for real. I do the
research, the design, the code, the deploy, and the
support. The company is Soxoa.
