Hello!
I would greatly appreciate if I can contribute in the development of your project.
I have experience working with web technologies such as JS using AngularJS, jQuery, knockoutJS, RestAPIs with PHP using SlimFramework, PHP ORM usando Mysql y Postgree database.
If you want to, I can organize your code using GIT using Github or Bitbucket, also I work using git-flow structure.
If there is anything that I can help you, please let me know.
