Web engineering focuses on the methodologies, techniques, and tools that are the foundation of Web application development and which support their design, development, evolution, and evaluation.
Any difference with a we developer?
Nothing. The two names are synonymous.
BUT if you’re going to make me split hairs I would say a Web Developer could be more focused on layout and styles — basically content sites. While a Web Engineer is building data-rich UIs/applications.
Different companies have different names for roles . If you compare a web developer job description with a web engineer one, they’ll be very similar and will be looking for pretty much the same skill set.
