I am sprachig for a Ionic 3 Hybrid developer, who can build my app. I have low budget but i can give you with my team a promise, that you will get our next projects as well with better budget.
All in all, i don't want to go in detail but in need Login/Sign Up function, chat, profile, premium account(pay), Notifications and 3 in app categories with functions. I need also admin panel, api, backend. I can provide from my last developer the source code, he has done some of these things ready. I also provide 90 percent of the design templates.
