Francois is the rare designer who thinks like a product leader. At Castos he shaped our product with great taste, sharp judgment, and a real feel for our customers’ problems. He ships quality work, communicates clearly, and makes everyone around him better. I’d hire him again in a heartbeat.

Francois has been incredible to work with. He has taste so his work is beautiful, but he also nails the technical side. He works fast and communicates clearly. We've been working with him for several years now. I even asked him if he'd come work full time for our company, which should tell you everything you need to know.
