    WordPress Consultant, Web Developer

    Canada - Last active: 8 hours ago - Tests: 4 - Portfolio: 2

    I distinguish myself from the competition by writing quality code. Everything I produce for you will be tested and polished. The work is complete only when I am satisfied that your request is properly fulfilled. We work together on your project. I am happy to educate and I will explain anything you do not understand about the project. Communication is important; I want you to know where the project is at all times and you will not just be told "it's fixed" or "it's done" without an explanation of what "it" is. I believe that the client/provider relationship should be transparent.
