Reliable platforms. Empowered teams. Costs under control.

Since 2016, I have helped large organisations—including BNP Paribas, Orange and Continental—build and evolve Kubernetes platforms across GitOps, multi-cloud, FinOps, observability and agentic AI. A developer by training, I work from application code through to the platform.

About

Developer by training, Platform Engineer by choice.

After graduating from INSA, I started as a full stack developer in finance (Amundi, Société Générale), then worked at cloud provider Numergy before moving into infrastructure in 2016. I never stopped coding; that experience still shapes how I design platforms.

My conviction: a successful platform leaves teams able to operate and evolve it independently, even after an engagement ends. I combine automation (GitOps, Infrastructure as Code), security by design, cost control and knowledge transfer to make that possible.

Since 2025 at BNP Paribas, I have been helping build agentic AI platforms on Kubernetes: LangGraph orchestration, observability and evaluation with LangSmith and Arize, and integration of Domino Data Lab.

Expertise

What I can do for you

I work as a long-term Platform Engineer or Tech Lead, through architecture audits or team coaching—from infrastructure to delivery—with one goal: a reliable platform your teams can continue to evolve.

  • Kubernetes Platform Engineering

    A production Kubernetes platform that is available, governed and straightforward to use: multi-tenancy, high availability and golden paths that help development teams deliver with confidence.

    • Kubernetes
    • Helm
    • Kyverno
    • Rancher
    • Karpenter
    • Keda

  • GitOps & Infrastructure as Code

    Traceable, repeatable changes: infrastructure and deployments are versioned, reviewed and automated. Rollbacks use Git rather than manual intervention.

    • ArgoCD
    • Terraform
    • GitLab CI
    • Argo Workflows
    • Jenkins

  • Cloud Architecture & FinOps

    AWS and GCP architectures sized for their workloads: identify underused resources, apply auto-scaling and optimise storage and data transfer while keeping availability and performance in view.

    • AWS
    • GCP
    • SNS/SQS
    • RDS
    • DynamoDB
    • DocumentDB

  • Security & Compliance

    Controls built into the platform—RBAC, Network Policies, image scanning, CIS hardening and network segmentation—to reduce risk and support audit preparation in regulated environments.

    • CKS
    • RBAC
    • Network Policies
    • CIS Benchmarks
    • Supply chain

  • Agentic AI Platforms & MLOps

    From proof of concept to an operable foundation: agent orchestration, LLM tracing and evaluation, governance and Kubernetes deployment to bring generative AI to business teams.

    • LangGraph
    • LangSmith
    • Arize
    • Domino Data Lab
    • Python

  • Observability

    Actionable metrics, logs and alerts to detect incidents earlier, speed up diagnosis and understand how services behave in production.

    • Prometheus
    • Grafana
    • Datadog
    • VictoriaMetrics
    • EFK

  • Tooling Development

    Versioned, maintainable internal tools, operators, CLIs and backend services—instead of one-off scripts. My developer background also lets me work directly on application code.

    • Go
    • Python
    • Java
    • Kotlin

  • Training & Coaching

    Training, pair-ops and architecture reviews to share Kubernetes and DevOps practices, so your teams can operate and evolve their platform independently.

    • Training
    • Audit
    • Benchmarks
    • Tech Lead
