About Sidet

Node.js back-end developer for 5 years at eTF1, I am currently looking for a mission where I can use my knowledge, improve my skills on the stacks used during this mission, and if possible learn new ones.
Otherwise, I have been a full-stack web developer for 10 years at cabestan, I participated in the evolution of the marketing campaign management platform. This web application is developed with the following technologies: coldfusion, javascript, nodejs, html, css, sql.
In recent years, I participated in the redesign of this platform, where I acquired knowledge in micro-services architecture, nodeJS, react, webcomponent, elm, elixir, postgresSQL, docker technologies.
Motivated as never before, I hope to find a mission where I can contribute to the success of the project thanks to my technical and interpersonal skills.
My team spirit, built through my sports background, and my sense of service, developed through my education and various experiences.
