So I'm a Java Dev used to work develop products on Google Clpud Platform. Technology stack used was Java, REST API/Webservices, Firebase, Google Cloud Datastore. Now that I've resigned from there (because of limoted opportunities) and joined a new company in another city.

And in new company I've been assigned to a project which is developed using Java Swing, SQL Server only.

So my question is:
Is it worth working on Java Swing which is a fairly old tech or should I look for another job: a webapp developer using Google Cloud Platform or AWS technology stack. What can be the wise move here in my case?

Really need a direction here guys. :)
