Back to original languageAbout Rubén
I am a self-taught and versatile technology professional with extensive experience in software development, systems architecture, and technical leadership.
I am passionate about challenges, and throughout my career, I have had the opportunity to face several high-caliber ones, such as leading the complete cloud migration of Bucmi.com, an experience that marked a before and after in my professional evolution.
I combine deep technical knowledge with a practical and problem-solving approach. Whether it's designing a new architecture from scratch or optimizing a critical production system, I adapt quickly and deliver effective solutions.
