I am searching here for an exceptional developer for JAVA for our not yet launched Android app. We programmed a Group chat app (with story function), which runs ok, but has the following issues:
- warm up lag when re waking or starting app
- sometimes scrolling lags
- connection takes pretty long
- delay when closing chats (hitting back button)
- delay when opening chats
- TEST THE APP UNDER LOAD (thousands of messages and groups) and make it perform with 60fps
I want a world class developer, who can bring this app to a complete new level by questioning:
- how can we get the butter smooth feeling Telegram has?
- do we need this many API call?
- do we use XMPP in the most appropriate way?
- what can we improve to make it ultra fast?
AS WELL AS IMPLEMENT ALL THE FIXES.
1 dev for Android, 1 dev for iOS, 1 additional expert for iOS, 1 additional expert for iOS and Android (10y experience), backend dev if needed
We dont use any chat APK
Many more tasks to come for this dev :-), ongoing project.
