About
I developed a love for pragmatism and philosophy throughout my career — a marvelous road that took me from Business Administration in Buenos Aires, Argentina, to Computer Science in Berlin, Germany, and now to co-founding a health-tech startup.
I've had the pleasure of working across very different industries — telecommunications, climate research, weather forecasting, video hosting, media & entertainment, agriculture, and now digital health — and in very different environments: academia, research institutions, conglomerates, networks and startups.
My personal goal is simple: to change the world... or die trying. One of the ways I've been doing this is by increasing work efficiency and empowering people to achieve what they thought was previously impossible.
Currently, I'm channeling this experience into building JarvisMed — a zero-knowledge, end-to-end encrypted health platform. It has deepened my passion for translating the complexities of healthcare into simple, powerful user experiences, a challenge I'm eager to take on at a larger scale.
This site gives you a glimpse into that path. Enjoy.
