Hi, I’m William, a UI/UX Designer who thrives in agile teams and has front-end awareness. I enjoy turning user insights into practical designs and prototypes using Figma, with a focus on usability and accessibility. I’ve worked on dashboards, SaaS platforms, and digital products, and I’m comfortable implementing UI in WordPress with Elementor while collaborating across stakeholders to ship usable features. In my day-to-day, I combine research, prototyping, and iterative testing to inform design decisions, always aiming to deliver delightful and accessible experiences. I’m eager to contribute to multidisciplinary teams and continue growing my skills in UX strategy, interaction design, and frontend collaboration.
