Oussama Cherif

Are you looking for someone to reduce your cloud costs, accelerate your deployments, or stabilize your production? I transform complex infrastructures into reliable and optimized systems.

5 years of experience in critical environments (BNP Paribas, PMU), with measurable results:

At BNP Paribas (2024):

• Reduction of deployment times by 45%

• Decrease in critical incidents by 30%

• Optimization of the IBM Cloud compute fleet by 40%

At PMU (2021-2023):

• Complete migration to AWS without service interruption (15 microservices on EKS)

• Transition from 2-3 releases per month to over 20 per week

• High availability architecture with auto-scaling and proactive monitoring

What I do concretely:

Audit your infrastructure to identify quick wins, then implement them using Terraform and industrialized CI/CD. I set up real monitoring (Dynatrace, ELK, Grafana) and transfer my skills to your teams so they can gain autonomy.

My stack:

Cloud: AWS (EKS, RDS Aurora, EC2, VPC) and IBM Cloud (IKS)

IaC: Terraform with reusable modules, remote state, workspaces

CI/CD: GitLab CI/CD, GitHub Actions

Kubernetes: Certified CKA administration, RBAC, Helm, Vault

Observability: Dynatrace, ELK Stack, Grafana, Prometheus

Certifications: AWS Solutions Architect Associate, Terraform Associate, CKA

Format sought:

I only work on long-term missions (minimum 6 months), ideally on a contract basis. This format allows for real infrastructure transformation and effective skills transfer to your teams.

Project types:

• Cloud infrastructure redesign (AWS, IBM Cloud)

• On-premise to cloud migration

• CI/CD and GitOps industrialization

• Cost optimization and FinOps implementation

• Reliability improvement for regulated environments
