- Built a site and API for a toll system. The application became the top payment channel for the service.

Experience
Friday's Guatemala Application
http://fridays.com.gt/beneficios.htmlThe application was created to replace the physical card for the loyalty program. The app allowed the owners have more control over who gets the rewards and the ability to note if there were any misuse of the program. The app was made available on Android and iOS.
Football Club Communications
A website was created for one of Guatemala's football clubs, with the specification of making it look similar to the Juventus F.C. site. Still, it had to be built on WordPress with a medium budget.
One of the challenges was to display everything correctly on all screen sizes.
The requirements also included creating software to synchronize the products with the SAP inventory and building new products when they arrived from SAP.

Courage to Run Cordova iOS App
This project was built on React for the front end; it connects to Laravel on the back end and uses a MySQL database to store all the information. Laravel is used to create the back end and the API that feeds the information to React. I also used Cordova to compile the React built into an iOS application.
