[ ABOUT ]

Associate Degree in Computer Science, passionate about clean code and agile solutions.

I graduated from the Jesús Obrero University Institute (IUJO) in May 2026 with an Associate Degree in Computer Science. At 21, I'm passionate about solving complex problems through clean code and agile implementations. I'm bilingual, fluent in Spanish (Native) and English (C1), which allows me to collaborate effectively in international teams. Outside of commercial programming, I dedicate time to volunteering, contributing my technical knowledge to social impact causes.
