A good WordPress Web Designer or Web Developer must have the necessary technical competence. He should have the basic technical skills that will act as the foundation on which the site will be built. A good developer will continually hone their skills and learn the new developments in the field.
It means that one should have a mindset for constantly learning. Those who are stagnant get stuck with the same techniques and designs. As everyone is aware, web technologies and designs are areas in which there is constant up-gradation. New versions of WordPress keep appearing and a good designer has to be adept to adapt to it. HTML5 and CSS3 have brought possibilities that were unimaginable a couple of years back.
A good WordPress professional has a wide repertoire of abilities and experiences in using plugins. He should be aware of all the possibilities of the design to aid E-commerce and E-marketing. He will be able to juggle with various projects which will be in various stages of completion at any given time. This calls for a lot of planning skills as well as confidence in being able to pace the jobs according to the time available.
WordPress experts have to deal with clients and get to know their minds and what they want their sites to do for their business. The various tasks have to be broken down into parts and each component will need to be done, perhaps separately, at various times. Each may require a different deadline and working time.
A good WordPress designer will have to be able to sell his design to his team as well as the client. He will have to explain its features and demonstrate what it will do. It will also involve a bit of marketing as clients for the projects have to be found and prices will have to be negotiated. There can be outside elements like hosting and security issues.
