Should you switch focus fully to Java backend (Spring Boot, REST, etc.)?

If you're looking for:

• More job openings

• Better chances at MNCs

• Growth and learning in scalable, enterprise-level systems

👉 Then yes, moving into Java backend with Spring Boot, REST APIs, etc. is a very strategic move. Java backend is widely used in fintech, enterprise SaaS, insurance, banking (you’re already in that domain via Finacle), etc.

Your Core Java skills give you a strong foundation—you just need to learn the ecosystem:

• Spring Boot

• JPA/Hibernate

• REST APIs

• Basic database handling (MySQL/Postgres)

• (Optional but helpful) Docker, Git, and a bit of CI/CD

Will your Android experience help at all in Java backend?

Yes—but mostly as transferable skills:

• You understand threading, memory management, system-level debugging.

• Your Core Java experience will help you quickly adapt to frameworks.

• Your work on interactive panels shows you're comfortable working closer to the OS, which is a plus in specialized roles.

However, when applying to backend roles, you’ll need to frame your past work to highlight Java logic, debugging, system integration, etc., while being honest about what you're learning now (Spring, REST, etc.).

Suggested Transition Plan

1. Short-Term (0–3 months):

   • Start building Spring Boot REST APIs (lots of free content out there, let me know if you want a learning path).

   • Create a few backend projects (e.g., employee management, expense tracker, etc.)

   • Push them to GitHub.

2. Mid-Term (3–6 months):

   • Learn about SQL and JPA/Hibernate.

   • Add basic Docker, Postman, Swagger usage.

   • Try mock interviews or backend-focused coding questions.

3. Job Hunt (6+ months):

   • Apply as a Junior Java Backend Developer or even Full Stack if you add basic frontend (e.g., React or Angular).

   • Mention Android experience as a unique strength but not the focus.
