About me

I am an Entrepreneur and a Software Engineer who has worked in the Tech industry for more than a decade. I love building quality communities and products that scale. I am currently the Co-Founder of Holberton School, a two-year program training highly skilled full-stack software engineers. Inspired by Progressive Education, our curriculum is based on a peer-learning and project-based approach, meaning that we have no formal teachers, no lectures, students learn by practicing and collaborating with their peers. What regular schools call cheating, we call it collaboration. Instead of acting as a gateway between knowledge and students, we act as mentors to guide our diverse group of students (40% women, 50% POC as of today) to become highly skilled Software Engineers. The type of Software Engineer who work for prestigious companies such as Tesla, Dropbox, NASA, LinkedIn, Apple…

Prior to Holberton School, I joined SlideShare in 2011 as a DevOps Engineer to support the infrastructure that served 3 billion slides every month. I was part of the team who contributed to the acquisition by LinkedIn in 2012, where I worked for 3 years.

I have a Master in Computer Science from the school SUPINFO, I studied in France, China (Hebei University of Technology) and the US (Dominican University).

I moved 13 times for the first 21 years of my life, I am since then living in San Francisco. When people ask me “what’s your hometown?”, I never know what to answer.

During my free time, I like to write, advise startups and travel. I love challenges, I have won the best API usage prize at TechCrunch Disrupt, went 25 meters underground in Paris Catacombs and climbed Mount Fuji at 3,776 meters above sea level. Discovering new places and cultures is something I am craving for, one of my life goals is to be able to combine work and travel to explore the world.
