on 2013 i was just googled a css style and edited a bit then i tried to put it on sale on codecanyon (rejected) same year i downloaded a ticket management system and i spent 6 weeks improving it (rejected) everyone told me you’re not a developer yet. why? they said you have to fight against time to became a success developer…on 2017 i got swift and objective c . i spend 10 weeks building a simple radio application, changed the UI 16 times (
still not look better ) tried 19 player to stream … finally my project got approved
