Familiarity with development tools like Git, RESTful APIs, Docker, and cloud platforms, as well as relevant certifications, is highly valuable. Excellent problem-solving, teamwork, and communication skills help you collaborate effectively and deliver robust solutions. These abilities are crucial for building scalable, secure, and maintainable backend services that power modern applications.

What are the typical challenges a JavaScript backend developer faces when scaling applications for high traffic?
