Hello.
I respect always client's opinion of project budget.
I have read your job description in detail and feel I can help your project.
Because I have 3+ years experience to develop mobile apps for both ios and android with native and hybrid.
My main skill is native(android studio and swift) but I have also good experience with hybrid(Xamarin, ionic ...).
So I can help you would get your app for both ios and android with native or hybrid.
I have good eyes and skill to get pixel-perfect screens.
And I have rich experience to build app based on Google Map, restapi, firebase, existing website, cryptocurrency and so on...
Please ping me in order to discuss this project.
Thanks for your care.
Best Regards...
