David Shusterman is a CEO and Founder at CaliAlfa. He possess expertise in c#, java, python, c, c++ and 15 more skills. Colleagues describe him as "Super intelligent individual. Sharp, Decisive, Organized, Clear & Hard Working. Knows where he is going. It has been pleasure to work with this man. Great expectations for the future - keep up!!!", "The first thing you notice about David is his big smile and his great sense of humor. But after less than a minute of a friendly introduction, he’s already six steps ahead of what you expected to be done. David is one of the most ambitious and self determinate persons you’ll ever get to meet and, hopefully for you, to work with. Nothing is done by him in less than the most professional way possible, always thinks ahead and always surprises with new ways of thinking. You can expect nothing other than the best of him.", and "In the last two years I have worked aside David in the IDF. Working with David was an extraordinary experience in all aspects. David passed among several teams during his service. I can examine every team that he had moved to in two different periods. The period that before David and the period after. David didn't left any team that he had moved to as it was before. He raised the level of every team, and turned it from good to excellent. David endowed efficient development methods, developed new products quickly, and simultaneously didn't stop to study and to teach. David knew how to get into any knowledge domain that was required, and to be the best source of knowledge in his field. David left a seal in our unit, and we already feel the absence of him."
