Hello there
I'm delphi software developer and UI/UX Designer , I used to deal with delphi since version 7 till 10.3 Rio , I used to deal with both VCL and FMX platforms , targeting Windows,Mac,iOS and Android too and Linux using third-party called FmxLinux.
We can achieve your concept using the great feature of Firemonkey (TLayout) which let us create responsive UI that works on every screen resolution.
You can check out my portfolio for some Firemonkey samples I have made .
Regards
