Hi.
So in a word, you need very creative worker who can work with minimum support and create very creative work, right?
My question is, do you already have backend web side api and server which is supporting the app? or should I build it?
I've read all your requirements in detail, I can do it very creatively, if you have only 3.5k
Please check my portfolio, reviews.
if you need more, I can give you 100s of my previous works, but it won't be needed.
