I've been working with Spring Boot for about 5 years, and I've learned a lot about backend development. I'm curious about what new areas in Java I should explore next to continue growing my skills and knowledge.

I suggest design a system from scratch, then run some load tests. You'll discover a ton about scalability and find interesting problems to solve as your project handles different traffic loads.
Think about building something you'd actually use. It’s a great way to apply what you’ve learned and to stay motivated!
You might want to dive into design principles! Understanding how to design software that can handle changes over a decade can get pretty complex and nuanced. It’ll take your skills to the next level.
Don't forget about cloud technologies! Learning about Cloud and Kubernetes can open up a lot of opportunities for you in the field.
How about contributing to open-source projects? It can really deepen your understanding of how Java libraries work and improve your coding skills even further.
