Build me a Mobile App

We have a WordPress website and a React Native mobile app which uses an API to fetch the WordPress data. It is published on Google Play Store and Apple's App Store. However, we are not happy with the performance and speed of the app. Therefore, we need someone to help us rebuilding it and have a mobile app without any of those problems. If you check our website and mobile app, you will see all the features we need. Although we define a fix payment for this job, it can be an ongoing contract as we will add new features and improvements every now and then. [login to view URL] Zeelamo
