I often call myself a jack of all trades and master of a few in the IT world. By this, I mean that I have experience in the full realm of software design, development and operation. I'm the person to turn to when you need someone who knows all the pieces and how they fit together, OS, RDBMS, Application Server, network, design, development, and operations. And I can explain it, in clear written and spoken language, both on the technical level and for end users. But if you need a master of the Oracle RDBMS, or Oracle Application Development Framework - that's me too.
