Mobilization is one of Poland's biggest mobile conferences - this year powered by SoftwareMill's copper sponsorship and our own iBeacon mobile app. The app idea started as a part of our support of the Confitura conference and we've been developing it ever since.
Plus, if you're a mobile developer and a solid back-end for your application, why not have a chat with us? We've got a decent experience building scalable infrastructure for Yap.TV and Emotiful, both with 90% mobile traffic. Just let us know at firstname.lastname@example.org and let's get the ball rolling!
