A software developer creates software applications for various platforms, including desktop, mobile, and embedded systems. They work with a wide range of programming languages and development environments, depending on the application’s requirements. Web developers, however, specialize in creating websites and web applications. They primarily use web-specific technologies like HTML, CSS, JavaScript, and backend languages such as PHP, Python, or Node.js. While there is overlap in their skill sets, software developers often have a broader focus, whereas web developers specialize in web technologies.
