We founded UaiTI in 2008, focused initially on Web Development Outsourcing.After 2010, we started to work with the development of Educational Technologies. Our most exciting project was EAD Builder, a tool that helped Teachers and Instructional Designers to create online courses without a lot of hassle that they would have working with complex tools like Flash and Illustrator. The platform also provided an image library with a great visual quality, something that they wouldn't have working with PowerPoint or similar tools.My main role was to set the product vision and roadmap, leading the development team to create great products, focused on customers needs and with as few resources as possible. To achieve that, we applied techniques of Lean Startup and Customer Development, and worked with agile methodologies like Scrum and with cutting-edge technologies. Our company was one of the firsts to use the MEAN Stack (MongoDB + Express + AngularJS + NodeJS) at the time. We eventually helped other Brazilian companies to start to work with this technology stack.In 2015, we merged UaiTI and its sister company, F6 Sistemas, and focused all teams only on one product: 4YouSee Digital Signage Software.Main Technical Projects:• A LMS (Learning Management System) based on Dokeos, using PHP, Yii framework, MySQL and Javascript• An eLearning content editor made with Javascript, AngularJS, FabricJS, HTML5, NodeJS, ExpressJS, MongoDB and Beanstalkd message queue• A CRM for textile industries made with PHP, CakePHP, Oracle DB, Java, Javascript, JQuery and Beanstalkd message queue• A microlocation application made with PHP, CakePHP, MySQL, iBeacons, PhoneGap and JavascriptTechnologies:• NodeJS• Javascript• ExpressJS• AngularJS• HTML5• MongoDB• PHP• CakePHP• ZendFramework• MySQL• Oracle• Java• AWS
