Certified GCP Professional Cloud Architect | Declared training organization (NDA 32591251159) | 15+ years of production experience
I help companies transition from costly or fragile infrastructure to scalable, observable, and maintainable cloud architecture, and then train their teams to be autonomous.
CURRENT MISSION: DECATHLON
OPS Engineer on the Gravitee API Management platform (~12,000 req/s, 99.999% SLA) and multi-cloud Kubernetes clusters (AWS, GCP, Azure, Alibaba Cloud). Implementation of large-scale OpenTelemetry trace collection. Zero-downtime deployments (Flagger/GitOps). Coaching and mentoring junior profiles within the team.
MY AREAS OF EXPERTISE
- Kubernetes & orchestration: architecture, scaling, hardening, monitoring
- Multi-provider cloud: GCP, AWS, Azure, Alibaba — critical migrations without downtime
- Infrastructure as Code: Terraform, Helm, GitOps
- Observability: Prometheus, OpenTelemetry
- CI/CD: GitLab CI, GitHub Actions, Jenkins
- API Management: Gravitee APIM (99.999% SLA, rate limiting, monitoring)
- DevSecOps: hardening, scanning, secrets management
TRAINING AND KNOWLEDGE TRANSFER
As a declared training organization, I conduct training in schools and companies on Kubernetes, Docker, and cloud infrastructure. At Decathlon, I coach junior profiles. Training teams is an integral part of my missions: I never do "black box" work — I document, I share knowledge, and I ensure your teams gain skills.
BACKGROUND AND ADAPTABILITY
Ministry of Defense (security, compliance), IT consulting firms, SaaS startups (Obypay, RadioKing), digital agencies (WhatsonWeb, 2BEVENTS) — very diverse contexts that have forged my ability to adapt and communicate with all profiles, from developers to the executive committee.
Pragmatic and passionate, I challenge architectural choices and am committed to quality. Each mission is a technical and human adventure.
