About Jeffrey Leon

Hello! I am a frontend web developer specialized in various UI technologies, particularly in Javascript. I have worked in significant companies in the technology sector, such as GoDaddy, and in the entertainment industry, such as Ticketmaster, both in the United States and Canada. I have also collaborated with renowned e-commerce companies in Chile, such as Ripley and Paris, where I have created robust applications and performed system migrations. For this, I primarily use ReactJS along with HTML5, CSS, Sass, Less, and frameworks like Bootstrap, Material UI, and Tailwind for graphical interface development. Currently, I am focused on the latest frontend trends, such as using Hooks in React, Redux and its middlewares, error handling with boundaries, utilization of portals, and implementing automated testing with tools like Jest, react testing library, and Cypress, among others. My goal is always to develop applications that consume APIs and other services in a clean and organized manner, following agile methodologies like Scrum and working as part of a team.
