As a seasoned PHP developer with over 6 years in the field, I understand how crucial it is to prioritize the user experience when updating ERP systems. Your project calls for enhancing dropdown functionality, implementing search features, working on multi-column dropdowns, ensuring seamless tab navigation, and making all changes without affecting existing functions - which are exactly the kind of skills I've honed over the years.
My expertise lies in Open-Source CMS-enabled Web-Solutions, eCommerce Web-Stores, Pixel Perfect Web-Design & Development, HTML, JQUERY and BOOTSTRAP templates. All these skills will undeniably benefit your project. Moreover, my experience working with various themes including Elementor-WPBakery-Beaver-SiteOrigin-Themify-Visual-Composer-Divi-Avada-Xtheme ensures that I have a comprehensive understanding of different system architectures and can debug efficiently, providing you a software free from bugs or redundant functions.
