During my role as Design Manager at Racional.cl, I led the end-to-end UX and high-fidelity UI design of a fast-growing investment app that was evolving at remarkable speed. Because the startup was only a few months old, we operated in weekly release cycles, constantly shipping new features and improvements while building a scalable design foundation for production. I established a design workflow that balanced rapid experimentation with a strong focus on clarity, consistency, and accessibility across every screen—crucial elements for an emerging fintech product.
To ensure that every critical flow performed flawlessly, I implemented usability testing through Maze and conducted user interviews that informed our design decisions in near real time. These insights helped refine high-stakes interactions such as onboarding, account funding, and investment execution. The result was an app that not only delivered a polished, high-fidelity experience but also achieved exceptional product-market fit—driving massive conversion rates and contributing to more than one million dollars in user-driven investments within the first year.
