Experience with tools like Spring Boot, RESTful APIs, version control systems (e.g., Git), and CI/CD pipelines is typically required.

They participate in sprint planning, code reviews, and daily stand-ups to ensure that both backend (Java) and frontend (React) components are seamlessly integrated. Effective communication and the ability to translate business requirements into technical solutions are essential, as is mentoring junior developers and driving best practices across the team.

What does a Senior Java React developer do?
