The first year was an amazing surprise - an explosion of inspiration and positive energy generated by local communities of tech experts, students, specialists, leaders and innovators. Second edition of our conference exceeded all expectations - with almost 400 attendees, 47 speakers and 7 tracks over two days it was hard to decide which opportunity deserves most attention.We studied hard, did our homework and hope to keep up the lucky streak.Third time's the charm - do you think we can make it the best one ever?
