My functions included setting up all the technological infrastructure of the company, development of software for internal use, and mobile applications for Android and iOS to give support to the veterinarians on their labors.

I developed several games using objective-c and frameworks such as cocos2D and box2D to make the front end, and php and mysql for the back end. In this job I participated in the development of Oh My Nuts!, both full and free version: (https://appsto.re/i6Fk3Hh, https://itun.es/i6F27C2) and two other games that are not in the apple store yet. I also.
