I got the opportunity to share my knowledge about the different design architectures for the development of mobile applications on Android (MVC, MVP, MVVM) and how to choose the one that suits better for our current project.

- Implemented the Android version for the application SaveUp, using the MVP architecture, to guarantee that further modification on the UI will not require to modify functionality already implemented.

- Cooperated in the modifications on the design of the current version on iOS, of SaveUp, to create a version for Android that follows the Android design guidelines.

- Implemented the different versions of the UI for the SaveUp application.

- Adapted the designs of the applications following the material Design guidelines for Android.

- Implemented the code, for the applications CQ and K.E.T., from scratch.

- Implemented the custom views for the apps to guarantee the correct presentation/interaction of the information.

- Solved conflicts in the requirements for a better client satisfaction.

- Coordinated the delivery of features for every sprint using the Scrum methodology.

In charge of developing, debug and modify mobile applications for Android platform, taking care of backwards compatibility, fragmentation of the platform versions, installation in different devices and the publication in Play Store.

- Modified the design for the UI, suggested by the Holo guidelines.

- Implemented the new version of the truStripes application, from scratch due to lost code.

- Coordinated the publication of the app on Play Store.

- Manage the publication of ew versions of the app.
