FAQ
Do you provide the full source code?
Yes, the complete, well-documented source code is included in every package. I provide the project in a structured format (Maven or Gradle) so you can easily manage and build it.
Which Java and Spring Boot versions do you use?
I typically work with the latest stable versions (Java 17 or 21 and Spring Boot 3.x). However, if your project requires a specific version for compatibility with existing systems, I can easily adapt to your requirements.
How do you handle database updates and migrations?
I use Flyway for database version control. This ensures that any changes to the database schema are tracked and can be applied seamlessly across different environments (Development, Testing, and Production) without data loss.
Can you integrate the backend with an Angular frontend?
Absolutely! I specialize in the Spring Boot + Angular stack. I can provide the API documentation (Swagger/OpenAPI) so your frontend can connect easily, or I can handle the integration for you in the Premium package.
Is the API secure?
Yes. Security is a priority. I implement Spring Security with JWT (JSON Web Tokens) to ensure that only authorized users can access your data and endpoints.
