Android & iOS senior full stack developer - Java / Swift / REST API / Big Data Machine Learning PHP

We launched the Android version of our health tracking app on the Play store about 6 months ago and are now looking for a full stack developer who is able to:

1) Review current Android code & develop new functions

2) Review current database and API setup

3) Plan and execute iOS development of the app

We have about 30k daily active users in the app and will scale to 1 million daily within the next 20 months. We need an experienced big data developer. Our users enter daily body symptoms: We want to eventually use that data (and apply machine learning) to enhance the user experience and make predictions about our users' health (e.g. giving the user advice on when to seek medical assistance). Our database architecture has to be built to allow this in the future.

We currently store the data inside MYSQL (just as a data backup - currently all logic is inside the APK, the local phone data is used for current functions inside the app). We need an expert who has seen big data mobile applications before and can restructure the setup and make sure our setup is scaleable for future use.

The android app is coded in Java ; we use PHP for database communication (currently setup in a wordpress interface, this obviously also has to get changed). Again, we need you to advise and make a decision on what is best here.

This is a long term project. We currently employ one Android developer who has built the current version of the app. We need a more experienced developer who can take over the project lead in all aspects.
