Blockchain Developer

Need a blockchain developer to make our own eth wallet and token. We also need this wallet integrated into user profile in our food mobile app which is made off react native. On the user profile they'll be able to see how much tokens/coins they have from using our mobile app. We have the amount each user gets from the pot for doing certain things in the app. We need this developed asap and for a good reasonable quote. As we grow and get capital this will become a long term project.
