RaspPi Developer [QT]

I need someone to create a single window app for RaspPi. App should manage and display certain data:

-current time in different cities/time zones
-camera feed[s] : our building currently has 3 cameras (rtsp) + 1 usb cam and we would like to see those feeds. Click on camera preview would pop-up a window showing the same feed but in higher quality.
-accuWeather info: fetching and/or showing weather info for the next 7 days and for the next 8hrs
-map

Start proposal with “RasPi’ ‘Masta” (without quotes). Sample layout idea will be provided. It should be in portrait mode, styled (dark mode), maybe developed with QT.
