On Thursday March 12, 2020, French President Emmanuel Macron announced the closure of schools from the following Monday.

In 3 days, a national logistics race was then organized to give the ability to front-line personnel (health workers but also cashiers, waste collectors, energy workers, etc.) to continue working while their children were at home.

In this talk, we'll discuss how Symfony was instrumental in this project and how you too can use your technology skills to improve the world around you.
