Hi,
I am an Android/Web Developer and I have been in the industry for more than two years now.
I like your project and I would like to help you make this app.
How I imagine it to be like is people who have the app can sign up either by social media or through registration and click to find their type of people to talk to anonymously.
Users will be given a random name each time they connect with someone so people will not be able to identify each other even if they meet on the app again so it remains completely anonymous.
I am offering you a low price of just 32 USD to develop the app since I am a new freelancer on the site and do not have much on my profile.
I would very much like this opportunity and to get that I am starting with such a low price.
But I can assure you that this does not mean shabby work, I want good ratings on my profile and I will offer you top notch work to deserve that.
Coming to the technical aspects, I will be using Firebase to make this chat app, this is a very fast cloud based technology that multiple chat apps have used worldwide and doing this would mean your app would remain seamless and easy to update if the need be.
So give this new freelancer a chance and you will be in for a pleasant surprise!
Looking forward to working with you!
