-# Internship report
-
 During the year, I developed a website for a new association in Toulouse related to TISA (Toulouse, Computer Science, Security and Association). I developed this website using the Svelte framework because I was intrigued by its promise of performance and simplicity of development.
 
 During this internship, I learned to use Svelte effectively and to set up a solid project architecture. I also had to work closely with the members of the association to understand their needs and vision for the website, in order to create a final product that met their expectations.
