Hi there,

I have extensive experience in integrating payment gateway.

I have 3+ years of experience in web industry.
I have designed as well as developed lots of websites for clients in recent past.
These websites are based on WordPress,Magento,Php,Joomla,Html,Css,JavaScript etc.
I also customized or redesigned websites for clients and add functionality in the website using the dynamic language commonly called Php.
