We are not often the first developers to work on a project. More often, we are the second or third developers hired.

Unfortunately, nearly all the Joomla component development projects we take over have serious code level issues. In this post, I'll cover two common mistakes we see and how they cost our clients time, money, and sanity if not addressed.
