System Design Interview – An insider's guide, Second Edition

I’m an entrepreneur with over 15 years of experience building global companies and digital products.

I founded Product School in 2014, which is the global leader in product training with a community of over two million members. All of our instructors are real-world Product Leaders working at top Silicon Valley companies including Google, Meta, Netflix, Airbnb, Uber, and Amazon.

Prior to Product School, I founded Floqq, the largest online education marketplace in Spanish and Portuguese at the time. Floqq joined the 500 Startups and Startup Chile accelerator programs.

My educational background includes Certificates in Global Business Management and Marketing from the University of California, Berkeley, a Bachelor’s Degree in Computer Science from the Universidad Complutense de Madrid and a Bachelor’s Degree in Industrial Engineering from the Universidad Pontificia de Salamanca.

I co-authored the Amazon bestseller The Product Book. Additionally, I've participated as a speaker in more than 1,000 events, conferences and classes around the world. 

Outside of work, I love skiing and playing tennis.

I’ve ranked the most popular writer on product management on Quota since 2015
