Hello!
I would greatly appreciate if I can contribute in the development of your site.
I have experience working with web technologies such as HTML5, JS, Angular(JS), Knockout(JS), PHP, SlimFramework(PHP), RestAPIs and MySQL.
The distributed version control system that I daily use is GIT using Github and Bitbucket, also I work using git-flow structure.
If there is anything that I can help you, please let me know.
