Hello Nishant,

Thanks for contacting Careers360.

Web Designer's Job: A web designer uses graphics and graphic design software (think Adobe,Photoshope,etc.) to create a look for the web. This design is then married with coding to bring it to life online.

The designer may not always be the person writing the code and in some cases can work independently of the team who will take a website design live.

Much of a designer’s job is creative and uses both intuition and imagination, often characteristics of people who are considered right-brained. People in this field may continue their educations in a variety of fields but are most commonly drawn to graphic design and the arts. Designers collect work portfolios to showcase their projects for potential employers.

Web Developer's Job: A web developer builds the backbone of websites, typically from the ground up, and knows languages specific to the web. HTML, Javascript, JQuery and CSS are among the tools in their kit. Developers, historically, don’t focus on making something look visually appealing but create websites with clean code and that are technically sound.

Web developers are often thought of as left-brained workers. Skills from technical ability and thinking to logic are an essential part of their repertoires. Web developers may have degrees in a variety of fields such as computer science or programming. Most employers will require a portfolio during the hiring process.

Front end and Back end developer: They are the two most fundamental parts of software engineering that play a significant role in web development. Frontend is what you see and interact with and backend is how all of it works. Frontend may refer to the graphical user interface whereas backend is that part of the website you cannot see or interact with. 

Hope this helps.

Good luck!
