About Me

Interpret, imagine, and implement: a journey connecting social sciences, management, and software architecture.

From economics and management to software architecture: interpreting, imagining, and implementing solutions with critical thought.

I was born in Buenos Aires (1986). My early educational background took place at the Carlos Pellegrini High School of Commerce and the University of Buenos Aires, where I studied Economics and taught Macroeconomics I for four years. Following a period of vocational exploration in journalism, editorial proofreading, and instructional design, in 2016 I decided to channel my analytical interests into technology, graduating with a Bachelor's Degree in Information Technology Management in 2025.

Since 2018, I have worked professionally as a software developer with special dedication to the .NET ecosystem (from .NET Framework 4.5 through .NET Core to modern versions .NET 8 and 9). Over the years, I have worked with monoliths and microservices, REST APIs, with and without ORMs, and relational and non-relational databases in industries such as fintech, logistics, consulting, and software factories. In every challenge, I believe the essential principle is to interpret, imagine, and implement: the constraints of each system define the boundaries of a solution that must always be innovative and tailor-made.

Perspective & Philosophy
"Being a software engineer means understanding that the outcome depends on a team-driven, intellectually intensive process with an immaterial result; thus, the essence of engineering goes beyond any single language, technology, methodology, or library."

Through my Substack publication, I aim to open discussion channels on the impact, ethics, and direction of computing technology. I firmly believe that if those of us who create solutions do not actively take part in debates on their future, that direction will end up being decided by others.
