I will develop java spring boot backend rest API and microservices

Need a solid, enterprise-grade Spring Boot backend for your project?

I will develop a secure Java Spring Boot REST API with Spring Security,

JWT authentication and a properly designed database layer structured

the way production Java teams actually build backends.

WHAT I WILL BUILD FOR YOU

Spring Boot REST API development

Spring Security with JWT authentication and role-based access

Spring Data JPA and Hibernate entity mapping

Database design PostgreSQL, MySQL or MongoDB

DTOs, validation and global exception handling

Layered architecture: controller, service, repository

Third-party API and payment gateway integration

Swagger / OpenAPI documentation

Debugging, refactoring and upgrading existing Spring Boot projects

Maven and Gradle configuration

WHY WORK WITH ME

Clean layered architecture, not everything stuffed in a controller

Proper Spring Security configuration not copy-pasted from a tutorial

Meaningful exception handling and validated request bodies

Code you or your team can actually maintain later

Clear updates and fast replies throughout the project

I also build NestJS backends, React web apps and Flutter mobile apps. Feel free to knoc me.
