The CEO of D&A Software about my continuation of the work on D&A Software's HP Palmtop software products

"Daniel joined our team in 2003 as a beta tester and quickly showed his abilities by promoting user interface improvements that elevated the quality of our programs significantly. He has a deep understanding of how humans interact with computers and software and this knowledge was very freely utilized while beta testing many of our programs.

He proposed many features that added value to the product, made them stand out and impress customers and users. Comments from customers about improvements suggested, and later coded by Daniel, included terms such as "polished", "agile", "anticipated my next move".

The author of the Notecase Pro outliner, founder of Virtual Sky Software, about our cooperation

"Regarding my Notecase project(s) I've received a great help by Daniel Hertrich. His help with program testing was invaluable, he is very thorough and detailed in his work and quickly managed to find a wide range of previously undetected bugs, some quite subtle and hard to find.

Another way this project profited are his ideas on improving the program usability, and suggestions for some nice features such as better export mechanism, customizing shortcuts.

Due to his personal interests in Sharp Zaurus platform, he even donated a Zaurus palmtop to the author to help porting the program."
