Back to original languageAbout Orphée
Hello and welcome to my profile.
As a Senior DevOps Consultant, I am passionate about modern infrastructures, designing complex, distributed, and resilient Cloud architectures, and implementing best DevOps practices for building robust and secure CI/CD pipelines.
My current technical expertise revolves around designing infrastructures in AWS and AZURE clouds through automation using IaC solutions like Terraform and Ansible to minimize human error. This includes managing build, delivery, and RUN within Kubernetes clusters, and designing secure CI/CD pipelines with Jenkins, Gitlab CI/CD, and GitHub Actions. I also have solid experience in implementing and maintaining operational systems using observability tools like Prometheus Operator and Grafana for CPU & RAM metrics monitoring, as well as log analysis with the ELK stack.
Below is a list of certifications I have successfully passed, with more advanced certifications currently in preparation:
- AWS Certified Solutions Architect Associate
- Kubernetes Certified Associate CKA
- Terraform Associate (003)
- Docker Certified Associate DCA
- AWS Certified Cloud Practitioner
Looking forward to connecting with you.
