Bernat Fortet, a highly technical designer with a background in game design, has spoken about the importance of collaboration between designers and engineers. He shared his early career challenges, including struggling to communicate effectively with engineers during his web design phase, but eventually learned to build trust through hands-on experience. As he transitioned from game design to startups, Bernat's relationship with engineering evolved, becoming more tightly coupled with a focus on clarity and clear communication. Knowing how to code has been useful for Bernat as a designer, allowing him to understand the technical aspects of his work and make informed decisions. He emphasizes the importance of creating a culture of design feedback, where designers can share their work openly and receive immediate feedback from users and teammates. To achieve this, Bernat uses various methods, including live streaming, design showcases, and open access to files, which he believes helps build confidence and exposes designers to new ideas.
