You will get secure authentication using Keycloak and OAuth2 for Spring Boot application
Project details
You will get a production-grade authentication and authorization system built with Keycloak and OAuth2, properly integrated into your Spring Boot application. This is not a basic configuration or copy-paste setup. I implement secure, scalable identity architecture with correct token validation, role-based access control, and clean separation between authentication and business logic.
What sets this project apart is the focus on long-term reliability and scalability. I design systems that support multi-environment deployment, future SSO expansion, and secure API protection from day one. Every configuration is documented, tested, and aligned with security best practices.
If you are building a SaaS platform, internal enterprise system, or scaling startup, this service ensures your authentication layer is robust, maintainable, and production-ready.

I know how IMPORTANT your project is—and how frustrating it can be to work with someone who just doesn’t get it.
That’s why I’m here.
While I’m new to Upwork, I bring over 5 years of real-world experience in full-stack software development. I’ve built everything from cloud-native SaaS platforms to internal enterprise systems, and I care about writing code that’s clean, maintainable, and ready to scale.
Here's what I can help you with:
🔧 Robust backends with Java & Spring Boot
🌐 Responsive frontends using Vue.js, React, and Nuxt.js
🖥️ Desktop applications with JavaFX
🛠️ Efficient data structures using PostgreSQL
☁️ Cloud deployments on AWS (EC2, RDS, Lambda, S3)
🚀 CI/CD pipelines and Git-based workflows
🤝 Clear communication, reliability, and fast turnarounds
I’m not just here to code—I’m here to solve problems, collaborate, and bring your vision to life.
💼 Attached is my portfolio, where you’ll find real-world projects I’ve built—like a full Procurement and Time Tracking System, among others. These weren’t just exercises—they’re actual systems used in production today.
So if you’re looking for a committed, experienced developer who’s ready to earn your trust and deliver real results, let’s connect.
I’m ready when you are.
