Designed a new and modern page that represented the company better. Designed all interfaces and implemented them with the appropriate technologies. Used Figma to design the interface and React to build it. Used GraphQL, in the BFF layer, with Node.js to construct APIs and establish communication between the front-end and back-end. Used PostgresSQL as a database. Delivered the entire page in two weeks. Crafted code that meets the internal standards for style, maintainability, and best practices for a highscale web environment. Maintained and advocated for these standards through code review. Worked closely with clients and cross-functional departments to communicate project statuses and proposals. That specific project has been impacting our target public since it was deployed. Successfully conquered new clients, communicating to the right people with the right message.
