Software Developer-Consultant Nationwide Childrens Hospital
Jill Lora, RHIA, Sr. Project Manager for Meaningful Use, Nationwide Childrens Hospital "I worked with David for 2-3 months on a project at Nationwide Children's Hospital. David had a very keen sense for understanding the business need and translating that into a working solution for us. David was extremely consientious, responsive and hard working. His math/analytical skill were very impressive on our project. We appreciated having David on our team." January 23, 2012
Andrew Brennan, Assistant Counsel, Special Projects Manager, Nationwide Childrens Hospital "David has been an extraordinary asset to our project. No matter what complicated feature we asked him to produce, he always said, "Sure, I know how to do that." --And he always did it in a few days, and did it right. His experience and expertise meant that our huge project was well within his capabilities to handle with finesse. By the end of the project, I stopped sitting at my desk struggling to figure out a complicated software problem—with his intelligence and logical mind, I knew he could figure it out in a fraction of the time I could. That left me free to get more work done. He anticipated and fixed problems before they had a chance to happen; his suggestions and recommendations were strategic and spot on (trust me—you need to listen when he says something is important!); and his designs are efficient, impressively bug-free, and easy to understand. I will continue to think of him first when we need a software developer." January 3, 2012
