    I have 14 years of experience in software development and believe there is a direct connection between design and the ease of use and efficacy of software. If the fundamental design is good then enhancements are very often natural extensions of it. I view testing as integral to development since the programmer will always have singular insight in understanding how to test his or her own software. I like to exceed expectations and I know from experience that doing so requires the ability to anticipate as well as solve problems.  less
