Founded in 2004, Facebook’s mission is to make the world more open and connected. People use Facebook to stay connected with friends and family, to discover what’s going on in the world and to share and express what matters to them. Connecting everyone, understanding the world and building the knowledge economy are huge technical challenges. Every month, more than 1 billion people around the world access Facebook through their mobile devices. Engineers at Facebook move fast and are constantly pushing the boundaries of what is possible on both native and mobile web platforms. We're always crafting new tools, build processes, and test frameworks to keep up the pace of mobile innovation - and we're actively open sourcing our work as we go along.
