I used 5 weeks to create a simple Shopify app on evening / weekends after my day job working hours. After launching it on Shopify App Store at mid January this year, I got my first paid subscriber after 3 weeks, and now I have around 15 paid subscribers.

I now spend 1-2 hours a day doing customer support / bug fixing for the app
