I will build a secure spring boot rest api backend with jwt auth

You need a backend. Not a prototype that breaks under real use.

I build REST APIs in Java and Spring Boot: proper layering, real

database persistence, validation, error handling, and documentation

that lets your frontend developer work without asking you questions.

WHAT YOU GET

 - REST endpoints designed around what your app actually does

 - Database schema, entities and repositories (Postgres, MySQL,

   Oracle or MongoDB)

 - JWT authentication and role-based access where you need it

 - Input validation and error responses that mean something

 - Swagger / OpenAPI documentation

 - Unit and integration tests

 - Dockerfile and setup instructions

HOW I WORK

  I write clean, layered code you can hand to another developer

  later. Controller, service, repository, properly separated. No

  business logic buried in a controller.

  You get the full source, not a black box.

Send me what your app needs to do and I'll tell you how many

endpoints that really is, and which package fits.
