10 Must-Do Spring Boot and Microservices Projects to Master Industry-Level Development
Introduction
Spring Boot and Microservices are at the core of modern backend development. Mastering these technologies requires hands-on experience beyond theory. The best way to gain expertise is by working on real-world projects that challenge your understanding of design principles, distributed systems, scalability, and performance optimization.
In this article, I will outline 10 must-do projects that will not only help you solidify your understanding of Spring Boot and Microservices but also make you industry-ready. Each project includes an outline of the requirements, core concepts you’ll learn, and the value it will add to your portfolio.
Follow-up articles will deep dive into each project, offering detailed implementation steps, diagrams, and code samples. For now, let’s kickstart the journey!
Check the links under each project to see the deed dive for implementation, eventually each project will have the details.
