About

I’m a software engineer and CEO of Vercel. I’m originally from Lanús, Buenos Aires, Argentina. I owe much of my career to the Web and Open Source.

I spent my early teens advocating for and teaching people how to use Linux and later developed a passion for JavaScript and Web development.

After joining the MooTools core team, I got my first full-time job as a frontend engineer at 18 years old and relocated to San Francisco, CA.

I started my first company Cloudup in SF which was later acquired by Automattic, the company behind WordPress, to power their editing and site building technology.

After being involved in creating numerous influential open source projects like Socket.IO and Mongoose, I saw the opportunity in creating tooling and cloud infrastructure to make the Web faster, with a focus on developer experience (DX).

Next.js and Vercel were born. Our platform now helps power the online presence of companies like Washington Post, Porsche, Under Armour and Nintendo.

Technical contributions

• I contributed to MooTools as part of their core team and led the development of the MooTools Forge package repository.
• Authored one of the first books on Node.js (“Smashing Node.js: JavaScript Everywhere”), after identifying the potential for JS to run on both server and client.
• My previous startup LearnBoost was one of the earliest adopters of Node.js in production. We made critical contributions to projects in the ecosystem like Express.js, Connect, Jade, Stylus, and many others.
• Authored Mongoose, which remains the most popular way of accessing MongoDB data in the JavaScript ecosystem.
• Authored Socket.IO, a popular library for real-time communication. Its underlying engine powers Notion’s realtime sync and the first Coinbase trading product.
• Authored Hyper, a cross-platform Terminal emulator built on Web technologies with over 42,000 daily active developers.
• Designed and co-authored Next.js, the most popular React framework. I later introduced it at the ViennaJS meetup and React Conf.
• I collaborated with Shu Ding on the design and conception of SWR.
• Built a popular file-sharing platform called Cloudup, building on realtime infrastructure for MongoDB I authored inspired by Firebase and a proprietary predecessor to Electron for cross-platform Web-based desktop apps.
• Conceived and co-authored a turn-based, multi-player virtual machine running a copy of Windows XP that went viral, inspired by Twitch plays Pokemon.
• Authored several other popular, smaller utilities that have accumulated billions of downloads, like ms, wifi-password, spot and slackin.
