Hello !

I'm Nicolas Mercier, entrepreneur & developer

Project management, UX/UI, Web / iOS development & sport

In a nutshell

I'm a french engineering student and an entrepreneur based in Lille (France), currently studying for passing a Master's degree in Web Engineering by 2017 at Ecole Centrale de Lille. Currently taking courses in e-business, project management, web marketing, SEO, financial audit, and of course development. I'm interested in many fields building projects around Web 2.0 !

IT & entrepreneurship fascinate me. Most of my free time is spent working for Capteev project. Mostly on thinking UX/UI, and developing for web using Symfony 3, Bootstrap & MongoDB. Also co-founded Walkin in 2014 and Juggle in 2015 but we finally had to give up on both projects. But it made me even more hungry !

Contact me if there is anything I can do to help you !
