Back to original languageAbout Julien
Since 2002, I've had the privilege of combining my career with my primary passion: development.
DevOps, Full Stack, Lead... whatever the term, I've always approached my assignments with the same mindset: a global vision and mastery of technologies in service of a project.
My various roles have also allowed me to gain extensive experience in managing and leading technical teams.
