Condomedia Inc

Development of different features using the following technologies: Ruby on Rails, Bootstrap, JavaScript, JQuery, CoffeeScript, AJAX, Heroku. Implement many models, entities and design and architectures to supply the customer requirements. This platform was built as a full-stack application, using bootstrap as front-end framework and to make the site full resposive. The project was like a private social media for admin and residents communication in condominiums in Canada and Colombia. As you can see, the dates between this company and Melollevo overlap, Condomedia was a Melollevo client at first, but they delegated the contract to me directly, so I worked in the 2 companies with the approval of both parties.
