I rewrote and redesign an industry leading CAD/CAM software application. The salesman of the software said, "This is what I've been wanting for years." The software is much more user-friendly, faster, offers more features, and more intuitive. Now the customer can literally begin using the software without days of training.
I complete projects in a timely manner. There have been some projects where I've accomplished more in a day compared to my predecessor working on it for weeks.
I have a full time programming job and apply for these jobs because I love to program. I look at each project/situation as a learning experience even if I've done something similar. I feel each company should have the software and/or tools that help their success and I can deliver that product.
