I've worked as the main developer in a live Magento 1.9 ecommerce with different tasks. I had the ownership of all the IT infrastructure (ubuntu cloud servers). As a full stack developer I've worked in every aspect of this ecommerce and developed new features. I've optimized the resource loading to increase the website performance and the increasing number of users month by month. I've profoundly change all the frontend template and developer new features like a membership program. I've changed all the checkout process increasing the speed, decreasing the number of clicks and changed the PSP. I've worked alongside the marketing and data analysis team to increase the ecommerce revenue and user experience. Furthermore I had to manage external collaborators tasks.
