Hello there! My name is Ravi and I am an experienced professional with over 18 years of expertise in programming, specifically utilizing PHP, MySQL, SEO, and various digital marketing platforms. I have the necessary skills and knowledge to successfully complete your project: upgrading your existing website's eCommerce platform from Zen Cart Version 1.5.x to its most recent version as well as fixing any glitches or errors associated with the old version.
I understand how important it is for you to have the UPS Shipping module fixed ASAP as this is one of the main issues preventing you from moving forward with your website development. Additionally, I have a strong understanding of various frameworks such as Magento, Laravel, CodeIgnitor, Joomla, Drupal, Symphony, WordPress and CakePHP which would be useful for you to consider when selecting an appropriate system for your needs.
I would be more than happy to discuss the project completion deadline further if needed. Please don't hesitate to reach out if you require further information or would like me to submit any relevant references or examples of my work. Thank you for considering my proposal!
