About William Freire
Currently working as a UI Designer at KaBuM!, I collaborate with the UX/UI Design team, focusing on visual solutions and digital products for the largest technology e-commerce in Latin America. My role involves developing new screens, maintaining existing prototypes, and creating design systems, primarily using Figma as my main tool.I hold a degree in Systems Analysis and Development from UNIP, along with certifications in UX and Figma from Alura and Udemy. Before joining KaBuM!, I worked as a Webmaster and UX/UI Designer at Fluix Performance, where I was responsible for SEO analysis, system and website development, and server management. One of my notable projects was developing an API for SLMANDIC's website, where I created the wireframe, design system, and interactive prototype after conducting data collection, user research, and workshops.I started my career at the age of 17 and have a deep passion for design, technology, and innovation. I am always eager to learn new skills, stay updated with market trends, and deliver high-quality solutions for clients and users. My goal is to contribute to the growth and excellence of KaBuM! and its UX/UI Design team.
