Profile

Cloud & DevOps Engineer with around 2 years of experience building secure, automated, and scalable cloud infrastructures using AWS, Kubernetes, and Terraform. I focus on DevSecOps practices, observability, and cost-efficiency to keep systems reliable and easy to operate.

With roughly 3 years in full-stack development, I bridge application concerns with cloud architecture—prioritizing clean design, automation, and CI/CD so teams can ship faster with confidence. As a Technical Lead at Day Truck, I drive cloud, DevOps, and observability initiatives across on-prem and cloud environments.

Languages: Arabic (native), French (C1), English (C1), German (B1). Location: Tunisia.
