This probably isn’t one of the most frequently asked questions, however I believe it to be a great question. This is such a great question because I am very hard pressed to think of a definitive answer. After thinking this over for a while, I have come up with a couple of questions that should help a young designer make the correct decision.
What is the goal of your portfolio site?
If the goal of your site is to be used as a tool to help you land a job with an agency then putting your resume online could be helpful. However, if you are trying to land freelance clients it is probably better to focus on your work and past clients rather than your resume.
Does your resume say something different?
If your resume contains some piece of information that really sets you apart from the typical design student then you should probably include it. Also if you feel that the design of your resume is strong in itself, then including it may be a benefit as well.
How strong is your portfolio / resume?
Determine if one item is significantly stronger than the other. If your resume is weaker than the perception your portfolio creates then you should not include it. It is really easy for an employer to read through a resume and see that you may be lacking something and cast you aside. It is a difficult to judge your own experience, so this may require the help of a trusted professional designer or mentor.
Overall, your objective should be to create the perception that you are a qualified and talented individual. If your resume in any way would hinder that objective, then it is probably best to leave it off of your portfolio site. While you will have to show it to a potential employer at some point, it is better to let them see the strength of your work first instead of letting them focus on what you may or may not be lacking in experience.
