A 24-hour non-profit event that encourages participants to develop web applications and mobile. Each team is composed of 4 people maximum. XCodingV4.0 will take place on April 27 and 28, 2019. With about 350 talented participants who are passionate about technology and programming, we will order 10 demonstrations and announce 3 winning teams. We will start with professional presentations followed by formations and then we plunge into the heart of the event: the coding. Our program is the idea and philosophy of "doing" instead of just read, memorize and introduce the mind entrepreneurship within the products of our candidates. Finally, the 3 solutions won will have the possibility launch their own Startup in collaboration with the incubators and investors.
