Effective communication is essential, as they must align backend functionality with frontend requirements and participate in code reviews, sprint planning, and troubleshooting sessions. This collaborative environment fosters learning and often provides opportunities to contribute across the tech stack, enhancing both technical and interpersonal skills.
