A good resume should start with a four-sentence summary:

- who am I ("ADBA with 3 years experience ...")

- what have I done ("I administered mission-critical databases for Acme Financial ...")

- why I am writing this ("I am looking for a challenging intermediate DBA position with a technology-oriented company...")

- what it means to you

The lattermost one ought to be tweaked for each company and hiring manager you are sending the resume to.

It helps to hint that you want to work for a manager who is looking for a problem solving ability, not for buzzwords on the resume.
