Here are some tips to help:
Prioritize your points and be results oriented.
Clearly show your technical skills by listing your technical knowledge first
so that a hiring manager doesn't have to look hard to find this info. Use
subcategories to make it easy for the reader to scan the document and pick out
key points (possible categories might include experience with web applications
and databases, technical certifications, hardware, operating systems,
networking/protocols, programming/languages, etc.)
A Technical Summary is also a good idea because it can contain keywords that
resume scanning software can pick up.
For those with lots of contract work in their background, you can use bullets
to list of your top projects, indicating the client, the scope of the project,
work performed and the benefits to the client.
