You will get Spring Boot Production-Ready Secure Backend
Project details
Get a production-ready Spring Boot SaaS backend with real business logic and secure multi-user access. Built for SaaS apps, internal tools, and fast MVP launches.
Includes a task management domain with proper data isolation — each user can access only their own data.
Authentication tiers:
• Basic – Single-user API with JWT login (no registration)
• Standard – JWT authentication with user registration, single role
• Advanced (Recommended) – OAuth2 / OpenID Connect with Keycloak (enterprise-grade identity management)
What you get:
• Secure REST API with real domain logic (tasks)
• Task ownership (per-user data isolation)
• Clean architecture (controller / service / repository)
• Stateless security
• Validation, error handling, pagination
• OpenAPI / Swagger documentation
• Docker + PostgreSQL ready
Best if you want a backend you can use immediately or transform into your own application.
Standard provides a typical JWT-based auth flow. Advanced adds centralized identity and role management with Keycloak, making it easier to extend with features like email verification or social login.
Custom features and integrations are available via custom offers.

About Majid
Senior Java Spring Boot Backend Developer
Doboj, Bosnia and Herzegovina - 9:48 pm local time
I focus on backend foundations that are easy to understand, easy to extend, and safe to use in real applications.
Clear scope, predictable delivery, and no overengineering.
I have 6+ years of professional experience working with Java and Spring Boot on backend systems and web applications.
My work typically includes:
- REST API design and implementation
- Spring Security (JWT, OAuth2)
- Clean project structure and configuration
- Docker-ready backend setups
I prefer clear communication and well-defined scope.
If you are not sure about technical choices, I can recommend the best approach before we start.
