I had worked with Karl a twice in two different companies. While the first time at Goldman was by accident, the second time at WeShop was by choice, and what a great choice it was! I truly enjoyed working with Karl for the wealth of positive qualities that he possesses. He is a very knowledgeable developer who is always looking for better solutions and alternatives. He is an excellent manager who listens to others before formulating an opinion. He is a fashionable technical professional who is able to hear different hats and quickly adapts to different roles. And lastly, Karl is an amiable person and member of any circle of people who is able to communicate with anyone and everyone and has no problem forming a connection. With all of this, if an opportunity comes up to work with Karl in the future, I will not think twice and will jump right in.
