Brad A.

Database design specialist.

United States - Tests: 2 - Portfolio: 1

I am a computer programmer with decades of experience using computers and peripherals in a variety of applications. I have worked independently on unique projects creating automated databases so that management (top-level to lower) can have useful data easily presented to them in a format that they can quickly use to make necessary adjustments. All of my work has met or exceeded expectations, and I do not stop until my employer is satisfied with my work. Before beginning a project, I will ensure that I understand well what is expected of me and work diligently and efficiently to accomplish it. Although I strive to do the best work possible, I realize that it may not be exactly what was wanted. Therefore, I welcome direction on necessary changes and strive to implement it quickly.
