Hello, I'm working as a iOS developer in a service based comapny from past three years. I graduated fron a tier 3 college in 2017. But now I wan't to move to a product based comapany, also I do not have much intrest in iOS development also considering the amount of opportunities in te field is less in product based comanies as compared to Fullstack and Backend.

I've really developed intrest in system design and Backend from past few days and I think that part is more challenging than iOS development. But there lies another thing that I have 3 YOE in it but now if I change my domain I have to start from scratch. So I'm really consused what to do next and how should I move forward with it.

Any advice or suggestions or some enlightnment to particular career path would be deeply appreciated.
