What is a Backend Engineer? Comprehensive Guide to Backend Development Specializations

A Backend Engineer is a software developer who specializes in server-side logic, databases, APIs, and overall architecture that powers web and mobile applications.

While frontend engineers focus on what users see and interact with (UI/UX), backend engineers ensure the application functions seamlessly behind the scenes.

This role is critical for building scalable, secure, and high-performance systems.
