Full-Stack FinTech App: Spring Boot 4, React, Devops & CI/CD

Full-Stack FinTech Masterclass: Spring Boot, React, & Production-Ready CI/CD

Course Description

Welcome to the ultimate course for aspiring and professional Java developers looking to master the modern financial technology (FinTech) stack. This is more than a simple to-do list app; you will build a complete, secure, and fully automated banking application from frontend to cloud deployment.

You will become a true Full-Stack expert by developing a lightning-fast Single-Page Application (SPA) with React on the frontend, which communicates with a robust, enterprise-grade backend built with Spring Boot.

Building a Secure, Banking API

The core of this course focuses on building secure financial transaction APIs. You will implement critical banking features including Deposit, Withdrawal, and Transfer APIs.

• Security Deep Dive: Master Spring Security to create a robust authentication system, manage roles and permissions, and implement JWT (JSON Web Token) for stateless, secure API access.

• Data Integrity: Design a reliable database schema using either MySQL or PostgreSQL, ensuring transaction integrity.

• Auditability: Learn to implement Auditor Routes and comprehensive logging to track and secure every user action—a non-negotiable requirement for any financial application.

Automation and Cloud Deployment Mastery (DevOps Focus)

The second half of the course focuses on taking your application to production using industry-standard DevOps practices. Say goodbye to manual deployments!

• Containerization: Learn to containerize your entire application (React frontend and Spring Boot backend) using Docker.

• CI/CD Pipeline: Implement continuous integration and continuous deployment (CI/CD) pipelines using GitHub Actions. This is your automated deployment system.

• Zero-Downtime Deployment: Witness an automated deployment process that pushes updates straight from GitHub to the cloud.

• AWS Integration: Integrate with Amazon Web Services (AWS), including the use of AWS S3 for secure file storage and managing static assets.

• User Notifications: Complete the professional ecosystem by integrating a dedicated SMTP email service to handle password resets, transaction confirmations, and system notifications.

By the end of this masterclass, you will have a production-ready project for your portfolio and the confidence to design, build, secure, and deploy modern, scalable Full-Stack applications. This is the complete skillset modern tech companies are hiring for.
