In my role, my primary responsibilities encompassed tasks related to form construction, component development, and, at times, graphical design. Notably, one of the most demanding projects involved the intricate integration of PHP's Symfony framework with a legacy React codebase. This task required a close working relationship with my supervisor to meticulously define the project's precise requirements. In addition to this integration challenge, a significant portion of my efforts was dedicated to layout design, further complicated by the dynamic design specifications inherent in the project. Another notable complexity arose in the development of a video player module, which, regrettably, remained unfinished. Additionally, I was tasked with creating a form generator for teachers. It's worth highlighting that the project featured an extensive CSS codebase written in SASS, devoid of any third-party UI libraries. This decision added another layer of intricacy to the project. In summary, my role entailed the creation of a highly sophisticated user interface within a technology stack comprising React, MobX, TypeScript, webpack (with particular challenges related to configuring PHP aspects), Jest, eslint, and prettier.
