What Does a Backend Developer Do?

A backend developer is responsible for the server-side logic, databases, APIs, and the integration of front-end elements built by other developers. Essentially, they are the architects behind the curtain, ensuring everything runs smoothly and securely. Whether it’s managing databases, developing RESTful APIs, or optimizing application performance, a backend developer plays a vital role in every tech product.
