Hi, I'm Julio, a Product Designer with 10+ years experience, I've worked with some of the world's most innovative companies. I specialise in human-centred UX, AI & UI design.

Hey there,

With over a decade of experience, I’ve designed apps, websites, and built design teams for both startups and large corporations. As a Principal and Lead Product Designer, I’ve refined my expertise in user experience, research, interface, and interaction design, continually applying and advancing best practices.

In leadership roles, I’ve coached and mentored designers both internally and externally, empowering them to realize their potential, define clear career trajectories, and plan for meaningful growth within their organizations.

Each project has presented unique challenges and valuable learning experiences, shaping my ability to deliver innovative, customer-focused solutions that drive business success.

In recent years at Canva, I’ve been deeply exploring the integration of AI technology into design tools, unlocking new possibilities for creative workflows. Let’s connect—I’m always keen to exchange ideas!
