Cloud SRE/DevOps with over 15 years of experience, I possess expertise in managing, automating, and securing cloud and system infrastructures on AWS, GCP, Azure, and IBM Cloud. My professional background has led me to manage cloud migration projects, ensure the availability and performance of critical platforms, and optimize costs and compliance of environments for major clients in the transport, banking, and telecommunications sectors. Also accustomed to collaborating with Node.js and Java development teams, I intervene in the automation of the backend application lifecycle (Spring Boot, REST API).
