Creatives often wear many hats to make ends meet, and they'll take on multiple freelance projects with strange titles like chief amazement officer, visual presentation specialist or PHP ninja.
This job title fiasco is why many creatives simply refer to themselves as "freelancers", but as far as your grandma is concerned that title means just as little as the rest.
You might as well call yourself vice president of the internet or, as this Pie Comic suggests, when granny asks you what you do just say "computers".
