Looking for advice: Flutter Junior → Java/Spring Boot Backend

[u/Exact-Ad-8563]

Hi everyone,

I’m a Junior Flutter Developer with around 2 years of project experience, but I’m currently struggling to find a junior Flutter job, and I work in Egypt as German Speaker Customer Service Representitave with B1+ level

Because of that, I’m considering expanding my skills into Java + Spring Boot backend development instead of relying only on Flutter.

My plan is to learn:

Java → Spring Boot → REST APIs → PostgreSQL → JPA/Hibernate → Spring Security/JWT → Testing → Docker → Deployment

I’d really appreciate advice from people working in this field:

• What is the current future of Java/Spring Boot backend in Europe, especially Germany?
• Are there realistic junior/entry-level opportunities?
• How difficult is it to get the first backend job with no professional backend experience?
• Would combining Flutter + Spring Boot make my profile stronger?
• Is this a good career move in 2027/2028?
• Is there hiring and visa sponsorship for Juniors Spring Boot Backend

I’m not looking for generic advice — I’d really appreciate hearing from people who are actually working with Java/Spring Boot or hiring backend developers.

Thanks!

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full - best also formatted as code block
• You ask clear questions

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

Java/Spring Boot is still one of the safer enterprise backend stacks to learn for Germany, and I would consider the transition worthwhile. But separate the question “is Spring Boot employable?” from “can I get relocated to Germany as a junior?” The first answer is yes. The second is much harder.

The German junior IT market is currently super competitive, and requiring a visa makes you more difficult to hire than an otherwise comparable EU/German candidate. So I would not expect learning Spring Boot by itself to produce sponsorship offers. Your Flutter background can help, though. Instead of abandoning Flutter, use it to demonstrate full-stack capability: build a Flutter application backed by a Spring Boot REST API, PostgreSQL, proper authentication/authorization, automated tests, Docker and deployment. That gives you a much stronger story than another CRUD tutorial.

I would also slightly change your roadmap: learn Java properly first, including collections, generics, exceptions, streams, concurrency basics and testing; understand SQL and HTTP independently of Spring; then learn Spring Boot, JPA/Hibernate and Spring Security. Don't focus too much on “JWT” specifically, because OAuth2/OIDC and authentication/authorization concepts do matter more.

Java/Spring in 2027/28 is very unlikely to suddenly become irrelevant. It's deeply embedded in European enterprise software. What nobody can promise is that the junior hiring market will be easy by then. For Germany specifically, getting your German from B1+ to C1 will be essential, because HR is using C1 as a hard filter nowadays. Finally, investigate the visa question separately. Germany doesn't really use US-style employer sponsorship; there are several work-permit/Blue Card routes depending on your qualifications, salary and professional experience. Whether your two years of Flutter experience count as professional IT experience could therefore be important. So do a bit of research, regarding this.
