I've been an IT professional for 25 years. I have a bachelor's degree in computer science. I've been doing this a very long time.
The idea for an application started on March 22. We launched the first version of ArriveCAN on April 29. That is incredibly fast by private sector standards. It was secure. It was on multiple platforms. It was successful, and it kept iterating. Even using any public servant, nobody can do it that quickly. This required skills that we did not have at the time.
