Need help in upskilling the tech stack

Hey everyone,
I’m currently working as a Backend Java Developer, having recently joined as an Associate Software Engineer in India. I’m facing some challenges in my current project. While I’ve been able to get by with basic coding skills last year, I’m now finding it difficult to keep up with the demands of the project with just this foundational knowledge. I’m eager to learn and improve, but I’m unsure where to start, what skills to focus on, or how to approach this. Any advice or suggestions would be incredibly helpful.
I aspire to become a stronger Java developer.
The tech stack we’re using in the project includes:
Java, Spring Boot, AWS, and PostgreSQL.
