About Youssoufou

Passionate about AWS Cloud and DevOps, I excel at using open-source technologies to automate infrastructure and deploy highly available applications. Every new feature I implement is an exciting adventure for me within the organization.

What I love most is the dynamic of teamwork, the uniqueness of each project, and the richness of exchanges with various stakeholders (architects, POs, pre-sales, clients, etc.).
