    https://itunes.apple.com/mx/app/sixpack-shortcuts-training/id960768458?mt=8

    This application was made on iOS Swift. (A module collaboration was also made in Android.) This application allows you to buy exercise programs, see the related videos, and keep control of your progress. You can schedule the programs and more. This is a project made in collaboration with the VanillaSys iOS team.

    It uses REST, a camera, an SQLite database, the AV Framework, Facebook, G+ SDK, a calendar, and push notifications.

    An Android application that holds the Beisbol (baseball) statistics of the Charros team of the LMP league.

    The application allows you to see the real-time scores of the games. You can also see the latest news, check the calendar, review the tweets related to the team, or take a picture and share it on Twitter.

    It uses REST, Facebook SDK, Twitter API, maps, directions, animations, a camera, a gallery, and push notifications.

  • AL NATURAL (Development)

    This application is made in Objective-C and provides space to handle the recipes provided by Chef Oropeza. The user can select his favorite recipe, have control of them, save the ingredients, see it's nutritional table, and create his own cookbook. It also provides a menu or exercise plan given the user profile. Other features: search for recipes, filter based on ingredients, and an online store.

  • SIGA (Development)
    https://www.siga.ipn.mx/

    This project dealt with the administrative control of IPN (an educational institution). I developed, in a team, the financial portion and designed it with the IPN rules in mind; specifically how money is distributed to the schools. For example, how the schools requested and spent their budgets, the reports, and the accounting.

    I collaborated on the design process, database implementation, and web implementation. I used MVC for the web and the Entity relationship for the database data.

  • SIICENDI (Development)

    This application was made for the benefit of IPN workers who were also parents of CENDI (kindergarten) children. It was made for the parents and teachers to use in managing the CENDI children.

    The application verifies data, checks availability, and provides a set of questionnaires so that the parent would have a health profile of their children. This also contains an activity and management system for the teachers.

    I developed it with ColdFusion and SQL for the database. I also collaborated on how the design was made.
