About

UX & Strategic Designer with 7+ years of experience creating user-centered digital products, brand and presentation design.

Currently pursuing a Master’s in UX/UI Design in Madrid, with strong skills in research, wireframing, prototyping, and scalable UI systems.

I’ve worked with startups, NGOs, and international teams, leading end-to-end design for websites, pitch decks, and brand experiences. My work has improved user engagement through UX-driven redesigns and clear, content-focused interfaces.

What differentiates me is my strategic approach: I connect business goals with user needs to design solutions that are both effective and meaningful. I’m comfortable collaborating remotely and cross-functionally, bringing structure, clarity, and intention to every project.

I worked as a freelancer designer for Slidegrin LLC; a company base on Huston, Texas, developing digital products and graphic materials such as corporate presentations, social media templates, infographics, branding, and iconography. These materials allow end users to intuitively edit and customize designs in tools like PowerPoint, Keynote, and Google Slides. Thanks to my designs, there has been a notable increase in template adoption, with an estimated rise in downloads and usage within the platform.

In collaboration with CONADECUS —Chile’s national consumer protection organization— we redesigned their institutional website to improve user experience, accessibility, and content clarity. Guided by IDEO’s Human-Centered Design methodology, the project was developed alongside the Communications and IT teams, combining insights from internal interviews, structural wireframing, and iterative design. The result is a more intuitive and service-oriented platform that strengthens CONADECUS’ digital presence and enhances its ability to support consumers online.
