Overview
A practical full stack path built for modern product teams: master Java 21 language features, design secure Spring Boot backends, and build responsive React.js UIs that consume your APIs. You’ll work through layered architecture, auth, databases, state management, and a portfolio-ready capstone.
Top features
- Write modern Java 21 code with records, virtual threads awareness, and clean OOP/design patterns.
- Build production-style Spring Boot REST APIs with JPA, validation, and Spring Security.
- Create React.js frontends with hooks, routing, and API integration against your backend.
- Deliver an end-to-end full stack project with auth, CRUD flows, and deployment basics.
