About Reda

My name is Reda and I have been working in the DevOps world for about 4 years. I have had the chance to work in 3 different entities of Orange Business Services in recent years, which has allowed me to develop a real capacity for adaptation as well as the opportunity to touch on several technologies in different contexts and for various needs.
I am comfortable with everything related to infrastructure as code (Terraform, Ansible), containerization (Docker, Kubernetes), setting up CI/CD pipelines with Gitlab CI/CD, github Actions and Jenkins as well as monitoring with Prometheus, Grafana and development with Python.
What I appreciate above all is the analysis phase of the need and the identification of appropriate solutions, the possibility of developing the existing and noticing thereafter an increase in productivity by the teams and a reduction in errors and repetitive manual tasks. I also like to ensure the application and infrastructure reliability of all the resources made available to developers and those used in PROD.
I always favor clear communication and transparency: my goal is that everyone knows where they are going and that the project moves forward in good spirits!
