Regards! I am relatively new to android (it does not mean that I do not have enthusiasm to undertake something new) I am restless and deepening of all systems to achieve better performance, but in desktop PC programming I have been more than 20 years old, currently I am working with an environment multiplatform, this means that what I develop can work on android, iphone, mac tables, and all platforms and versions, I am interested in your proposal and if you consider that my services and knowledge meet your expectations, I ask you to let me know, I will put everything the effort in your apps .. is sincerely appreciated!
