Hello,
My skype name is steve_computer. I'm a web developer located in Toronto, Canada and an expert in Wordpress and Magento. I've recently developed Magento extensions (CSV product export for frontend customers, order fees, lowstock product alert, new product alert, Magento API access for dropship customers), developed magento themes, installed and upgraded Magento from 1.9.1.1 to 1.9.2.4 for a client (NOT on upwork site). All security update patches were installed. I can do the same or more for you. Specifically, I'll write custom SQL query for customer attribute updates. I'll ensure they're working flawlessly even go over fixing a little bit more for bug fix completion. I've done many of similar tasks so they are quite routine jobs for me. Please feel free to view my recent jobs on my profile page. I've been making and customize Wordpress, Joomla, Magento, Zencart, Prestashop, Drupal sites for clients many times over so I know it how to make them very well. I had excellent Magento, Wordpress experience in the past as I helped many clients to customize shopping carts, theme template and plugin extension.
I can start right now and finish the job quickly. I'm an expert in WordPress, Zencart, Magento and Joomla site all aspects including MySQL, custom modules, theme templates, customized HTML pages.
