David Matejcek

I am a Java EE and Jakarta EE developer since 2005, rescuing "dead horse projects" especially when it is widely accepted that it is not possible. Do you know that relief when you reduce complexity? Do you know that happiness of all those side effects which were not expected at all? I mean ... not those bad side effects, zombies attacking from your suite case - I mean positive side effects. You just wanted to understand the code, so you changed formatting, renamed variables, methods, reduced their visibility, understood the API, started moving things ... and when you understood, somehow it worked with a better performance. Something broke? Easier to fix than to fix a typo before your changes. You even have fun of writing tests, huh! Found bug is a good bug. Are you happy? I am!
