Bio
Paul D'Ambra
Karl had a transformative impact on whatever he worked on. Whether it was product thinking and direction, large-scale technology changes, how we write code, refactoring, and more. I learned so much even only from watching him. Most wonderfully I received consistently useful and valuable feedback and support. I'm a better engineer when I stop and remember to ask myself: "What would Karl do?"
Neil Kakkar
I was pretty skeptical of the term '10x engineer' until I met Karl and got to work with him. He's one of the most talented engineers I've ever seen, and I'm always pleasantly surprised by the breadth of knowledge and ideas Karl brings to the table. Perhaps most importantly to me, Karl never treated me as a "junior who needs to be taught". Rather, we'd discuss trade-offs and hone each other's thinking (well not surprisingly, Karl's solutions tended to be the best ones). Any startup that manages to hire Karl will probably increase their chances of success significantly.
