1. Does a Front End Developer of desktop software need the same skills as a Front End Developer for the web?

In software development, Front End may refer to the presentation layer, a user interface rather than the data access layer. In web development, the client side is usually called the front end, and the server side is called the back end. As these principles differ, the skill set differs. The technologies used for software development depend on the OS. For example, a developer might use the C programming language and the Win32 API to code for Windows, or Linux “kernel-user space” API coding for Linux software, or a cross-platform library, such as Qt (for C++). Also, there are some frameworks that allow building Desktop apps using typical Web Front End technologies: HTML, CSS, and JavaScript (for example, Electron).
You don't need a developer to make a simple website using a template theme and WordPress. A job as a WordPress developer usually means creation of customized themes and plugins.
Although HTML, CSS, and JavaScript are the three pillars of the front end , a developer must be able to use the jQuery library. As a rule, knowledge of CSS preprocessors, LESS/SASS, is also required.
Create a vacancy with a list of responsibilities and skills relevant to your project. Post it on job boards and on specialized Facebook groups or Telegram channels for IT specialists. In this way, you can find a junior specialist, or maybe a middle front end developer . Experienced professionals are rarely actively looking for a job. You need to contact them through LinkedIn and find ways to interest them. If you need an experienced front end developer , it's better to entrust the search to a professional recruitment agency.
