Hello,
I have 7+ years of experience in development using WHMCS.
I have created many modules, addons & hooks scripts for WHMCS. I am good at Smarty template engine that WHMCS uses. I am good with CSS as well.
Can you please PM me the website, so that I can have a look.
I can put in 8hrs/day. I use the freelancer desktop screenshot app, so that you can verify the works.
I am good with GIT as well.
I normally do WHMCS based works, because I specialise in it. Please check my reviews here: https://www.freelancer.com/u/phpizephing
