"Working with Rocky is amazing. He brings a next-level amount of enthusiasm and positivity to the work. We collaborated on a financial education project together at Cash App, and Rocky super-charged our momentum up by keeping the big picture front and center. He frequently reminded us how effectiveness in our focused use case could translate to the rest of our products. As an engineer focused on minute details, I really appreciated how Rocky tied everything to a larger vision."
"One of the very best design leaders I've had the pleasure of working with. Passionate, generous, insightful, strategic, capable, influential, kind, and above all else: Irreplaceable."
"Rocky and I worked together at Cash App for a little over two years. What was most impressive was how he always led with empathy and respect for his teammates. He consistently showed up for the entire design team, and always asked the hard questions. His feedback was always well thought out, and he frequently pushed us all to look at the bigger picture. Any design team would be lucky to have Rocky calling the shots!"
"Rocky brings in a lot of energy and vision to the entire team. His passion and human-first approach was contagious. He is a great leader and key member for the entire group: from co-creating our roadmap, to defining and creating data driven user experiences. He has a remarkable ability to absorb feedback effectively, and collaborating with him is a pleasure."
"Rocky was the design lead and played a big role setting the vision and roadmap for the entire org. As an engineering manager, I valued Rocky's high level vision, but also being able to get into the weeds and break things down at a more functional level. He always brought a positive and enthusiastic energy. It was infectious. Rocky was able to level up a lot of other folks in the org with his mentorship and advice."
"Rocky stands out as one of the most enthusiastic and inspiring design leaders I've had the privilege to collaborate with. His leadership style is characterized by empathy and a relentless pursuit of truth. His blend of expertise, passion, and collaborative spirit makes him an invaluable asset to any organization."
