Front End vs. Back End Developer; which of these two top tech jobs is better for you?

Front-End and Back-End developers play distinct yet complementary roles in web development. As to which is better for you, well, the answer to that will come down to personal choice - and how your skills fit into the not insignificant number of responsibilities which each has!

In short, Front-End Developers ensure that users have a visually appealing and interactive experience – the ‘look and feel’, while Back-End Developers ensure that the application functions smoothly ‘behind-the-scenes.’ Understanding what these roles entail can help aspiring technology professionals in the UK choose a path that aligns with their skills and interests, ultimately contributing to the creation of robust and engaging web applications.
