What I'm looking for

I’m looking for a team where I can own UX/UI end-to-end—design systems, prototypes, and responsive front-end—while partnering to improve usability, accessibility, and performance.

I’m a UX/UI Designer and Web Developer with over 4 years of experience creating user-centered interfaces, developing responsive websites, and implementing modular Design Systems. I bring hands-on expertise in prototyping, wireframing, information architecture, and usability testing, with a clear focus on accessibility and performance optimization.

In my UX Advisor role at Klak, I created and maintained a modular design system that increases design-adjustment speed by 20%, and I deliver strategic UX consulting to improve platform usability, user experience, and accessibility. I’ve also developed responsive websites based on Figma prototypes, implementing microinteractions with HTML, CSS, and JavaScript to improve usability and performance. At LMV Software Factory, I led a corporate website redesign that achieved a Lighthouse performance score of 90+ and mentored team members in HTML, CSS, and WordPress best practices.

Through freelance work and client projects, I’ve designed and built intuitive, visually appealing user interfaces while managing end-to-end delivery—from concept to deployment—on time and within budget. I enjoy turning complex requirements into clear, usable experiences, and I’m motivated by building design systems that help teams move faster without sacrificing quality.
