Hello, i havent worked in Laravel before, but i have developed my own CMS in Symfony 2, so im quite used to their framework. As for github, i use it on a daily basis. I might not be so profficient in Laravel, but the research time i do wont be included in the hours i work, so you wont be at a loss if i have to google something.
Anyway, i dont think its a big of a leap for me, as i worked in a lot of frameworks. Contact me if you're interested in more details.
With regards, Nemanja
