Having worked as a Full Stack Developer for over 7 years, I have acquired extensive skills and knowledge to handle your e-commerce project with utmost professionalism. From the onset, I would ensure that all 125,000 products are properly categorized and subcategorized thereby enabling a seamless user experience. Drawing from my proficiency in HTML, CSS, JavaScript, React, Node.js, and PHP, I am confident in implementing the necessary AI smart search feature to ensure that product searches yield accurate results for your customers.
Moreover, my expertise extends beyond the retail sector as I have successfully created similar auction functionalities on different platforms before. Therefore, I understand the intricate details required for an efficient multivendor system. Additionally, maintaining an organized database will be of prime importance in both the retail and auction parts of your website. I assure you regular backups and an effective tracking system to keep tabs on customer search history,purchases, as well as vendors' inventory to provide relevant suggestions to customers on items matching their interests.
