Nicolas works on Symfony, with two sides to his contributions. On the open-source side, he's been submitting new features and bug fixes almost daily for 5 years. He puts a lot of efforts on making Symfony fast, easy to use and well designed, all at the same time. On the business side, he leads the ambition to create a sustainable company supporting and supported directly by the Symfony ecosystem. He previously worked as CTO for Blackfire.io, the PHP profiler that we were all missing and you should definitively try.
