Kotlin is compiled throw the JVM like many other languages Java , Grovvy and more

So you can write Kotlin code and run it in different environments thanks to the JVM

Now it replaced Java in Android development and in back end stack used by Java like Spring framework also used now rather than Java

You can build desktop app also like Java

Consider it as an updated version on Java

There is also KMP in android development which is a cross-platform tech

In general it's a great OOP language you can use

Regarding getting a job you have to focus on a stack that uses Kotlin

as I mentioned Android development mainly , Back end with spring framework or any JVM language based framework and also KMP but it's not so popular now in Egypt

Regarding the age just focus on being good & professional on what you can do

Age can be an obstacle in some companies and may be not in others

There are other options like freelancing or working remotely with abroad companies

Honestly it's not that easy so that you should be good at what you're doing

Best of luck
