Desktop Application Jobs

I’m looking to develop a user interface similar to nordvpn showing the active locations using a vpn service. I need the application to work on desktop (mac and windows) and Android and iOS. The vpn servers should come from a vpn service that lets us use their servers. I have the onboarding (login/registration already built). Please let me know if you have any open to different suggestions to make this happen as quick as possible.

I am looking to create a MacOS Application with the goal of helping users customize shortcuts based on their needs. The application should be able to quickly open new desktops using MacBook's Mission Control feature, be able to run a list of commands customizable by the user to perform one completed task (Similar to the application Shortcuts). The application should provide users with the ability to customize to their preferences, as well as enjoy automatic updates and security features. The programming language I want to use for this application is Swift.
