Complain to me about your backend development problems!

Hey!

If you wouldn't mind, could you please complain to me about your the most hateful pains and problems in backend development? Just one thought about these problems have to make you feel uncomfortable. If you share your pains with me, I’ll try to solve it!

The thing is I really want to create a solution for backend developers and it would be great if you guys could help me with the problem.

I’ve already have 2 products (the second one is under development) but I still have possibilities to create another product.
