We are a StartUp from Germany and we have an iOS VPN App which needs some optimization as well as some additional features. The optimization part is especially for the VPN tunnel and also for the NetworkExtension. Right now it takes up too much memory and crashes from time to time. The additional features will be discussed privately but you should be able to work with the OneSignal api. So skillset: - iOS vpn master - iOS push genius Best, Chris
