Hi Sir.
As an experienced Javascript expert, it is very interesting to me.
I have been working on several website & CMS such yours for over 5+ years.
I have powerful website design skills and full knowledge on several languages on such as HTML, CSS, PHP, Javascript etc...

I think i could be the right person for your project, because of my past experience and skills.
I would be very appreciated if i have a chance to show you how could i help you to meet your goal.
Thank you.
