David an excellent coder with great technical skills but doesn't have the experience to consider/ask how his work will impact existing website pages. David should consider that he's being hired to for his knowledge and skill and thus is responsible for asking questions that will keep his code working properly with both exsiting code and other code that he's created for his clients. Do the above David, and your reasoning skills will match your coding skills making you a top notch pro.
