Hola! Hi! Hallo!

I am an experienced entrepreneur with a background in computer science, specializing in driving and growing agile businesses through innovation.

With 10 years in management roles, I have been responsible for strategic decisions around growth, people, product, recruitment, tech stack and business operations. I am a reliable and committed team member, trained by top business accelerators such as 500 Startups & Startup Chile.

As a co-founder of EntrenaYa, a B2C & B2B fitness subscriptions marketplace with over 800 gyms and fitness centers in LATAM, I have honed my skills in leadership, goal-oriented thinking, and effective communication.

I'm a Sagittarius, a music lover, father, a cook, and a wine geek. I lately am, like many others, particularly interested in the field of Machine Learning.
