Looking for a DevOps or Platform Engineer who can structure and industrialize your production environments? I help you move from a handcrafted infrastructure to a scalable, automated, and reliable platform.
Specifically, I focus on:
▸ Building internal platforms — I design Internal Developer Platforms on Kubernetes (Helm templates, automated compute, GitOps) so your developers and Data Scientists can deploy autonomously, without depending on an ops ticket for every deployment.
▸ Industrializing your CI/CD pipelines — GitHub Actions, Jenkins, Argo CD: I standardize your build, test, and deployment workflows to make every production deployment repeatable and traceable.
▸ System observability and reliability — ELK, Grafana, OpenTelemetry: I set up dashboards and alerting so you can detect incidents before your users do.
▸ Securing your environments — Vault, Cyphertrust, dynamic certificate management: your secrets and sensitive data are protected by design.
What sets me apart: I built a centralized MLOps platform used by all of Société Générale's Data Scientists (10 DataLabs, +50 use cases in production, on-premise and Azure infrastructure). I don't just lay down technical bricks — I structure, standardize, and ensure longevity.
Types of missions I accept: internal platform construction, Kubernetes migration, CI/CD implementation, MLOps industrialization, observability audit, DevOps/Platform reinforcement for existing teams.
Stack: Kubernetes, Helm, Docker, Terraform, Ansible, Azure, GitHub Actions, Jenkins, Argo CD, MLflow, Airflow, Databricks, ELK, Grafana, OpenTelemetry, Kafka, PostgreSQL, Vault, Python, Bash
