Familiarity with frameworks (such as Spring or Express), RESTful API development, version control systems (like Git), and containerization tools (like Docker) is typically required. Effective problem-solving, collaboration, and clear communication are standout soft skills for this role. These abilities are crucial for building reliable, scalable backend systems and working efficiently within development teams.

Collaboration with frontend developers, DevOps engineers, and QA testers is essential to ensure smooth deployments and consistent user experiences. Staying up-to-date with new frameworks and technologies, while balancing project deadlines, is also a key part of the role.
