About Me

I grew up in a rural region of Guatemala, where I learned that collaboration, empathy, and a passion for sharing knowledge can transform communities. This belief guided me to lead human-centered projects like Alfabetizate, bringing digital literacy tools to underserved areas, and Explorax, an edutainment app blending curiosity and play to teach scientific and cultural concepts.

I thrive at the intersection of technical rigor and genuine user empathy: I deliver precise code within agile teams while always listening to—and adapting for—the real needs of end users. My "learn-by-doing" mindset pushes me to embrace new challenges, iterate quickly, and share each advancement with my community, because I believe that the most valuable technology is the one that empowers others to grow.
