Mern stack and Java spring boot are over saturated fields
Which technology to learn for less competition and high pay?
Why Java SpringBoot is saturated? . Mern is learner by even art graduate. But Java SpringBoot is tuff right?
All backend is same you need to understand concurrency.golang is easy to write concurrency than Java
Req.body.username is not considered as backend.system design with security needs to be kept in mind while designing even mern application
Less competition does not equate to high pay. If you're an okay Spring Boot developer, you might get higher pay than if you're an amazing Salesforce developer. Finding a niche is good, but do keep in touch with the tech stacks that are popular.
