About

As a creative and results-driven UX Designer with a background in Computer Science, I am passionate about simplifying over-complicated design solutions that not only meet business goals but also elevate user experiences. With expertise in user flows, prototypes, and usability testing, I thrive on collaborating with cross-functional teams in Agile environments to deliver impactful designs. My technical skills in Python, HTML/CSS, JavaScript, and design tools like Figma, Sketch, and Adobe Creative Suite enable me to bridge the gap between design and development, ensuring that each project I work on is both visually compelling and technically sound. I have successfully led high-impact projects, including a $1.63 million security software transition that improved operational efficiency and reduced security costs, and a contract renewal project that saved Cigna on average $20 million a year. I believe in the power of design research and stakeholder interviews to deeply understand user needs, which has led to tangible improvements like a significant reduction in user fatigue across applications I’ve worked on. I’m also experienced in developing and enhancing design systems for consistency and efficiency. Fluent in English, Spanish, I bring a global perspective to my work and am dedicated to fostering collaboration, innovation, and inclusivity in every design project. Let’s connect and explore how we can create meaningful, user-centered solutions together!
