Hi,
I'm a software engineer and I have extensive back end experience. Feel free to look at my profile (and my LinkedIn profile, just search for "Mirza Suljić", I'm not allowed to link it here).
In case you just want to know my skillset, it's Java, PHP, MySQL, HTML, CSS, jQuery.
I'm currently free so I could devote 40 hours a week to your project.
Feel free to contact me any time,
Mirza
