Strobe

The Strobe platform was launched in September 2011 , aiming to empower developers in creating HTML5 applications for desktops, smartphones, and tablets. The primary objective of the platform was to offer a comprehensive suite of tools for building, deploying, and hosting web applications. My involvement with the team began in June 2011, where I contributed to integrating the platform with social networks such as Facebook and Twitter. I had the privilege of working alongside a remarkable team consisting of individuals like Yehuda Katz, Carl Lerche, José Valim, Peter Wagenet, Piotr Sarnacki, and many other talented individuals. In November 2011, the platform was acquired by Facebook.
