“Janusz was a hero. In the late stages of an iOS project i had some urgent bugs arise. Janusz worked quickly and efficiently to find the solutions and discuss with the other developers on the project how to make the fixes along with fixing some last minute issues just prior to submission. Janusz having involvement has given me peace of mind that some of the critical features of the app will stand up against the Apple review process. I will definitely hope to work with Janusz again on iOS projects.”
