Callum was such a great person to collaborate with. He has a big-picture vision and was always willing to walk me through his ideas and the reasoning behind them. Even though he wasn't familiar with UX, he was open-minded about the process and gave thoughtful feedback every step of the way. It felt like our work was just the tip of the iceberg- one very small piece of a much larger, ambitious vision. I’m excited to see where he takes it next and wish him all the best as he continues to bring this concept to life.
