While David started at Microsoft back in 2004, for the past decade he's focused on identity and access management, which led him down the path of helping customers build some of the most complex federation architectures for single sign-on and SaaS applications. Back 6 years ago, David decided that he wanted to use his collective experience and knowledge to help shape the future of Azure AD by working for the engineering division. Nowadays, David assists customers on their Zero Trust journey by helping them consolidate all their applications on Azure AD and dismantling the federation architectures that he once helped them build.
