Looking for a DevOps Engineer?
You are in the right place 👇
👨💻 I am a DevOps Engineer with 12+ years of experience in delivery, platform reliability, and application modernization (Azure, Kubernetes, GitOps, CI/CD, Ansible, Java/Spring, Angular, Node.js, Bash, observability).
I cover end-to-end: architecture 🏗️, CI/CD 🚀, GitOps 🔁, SRE/observability 📈, automation 🤖, cloud/legacy migrations ☁️↔️🏢, and team support 🤝.
🏭 Sectors: insurance, public sector (Customs), transport/railway, logistics/supply chain, accounting/management, education/training.
🏢 References: MAIF, SNCF Réseau, Capgemini, Sopra Steria, DSIA.
I am able to:
- ☁️ Design & operate hybrid Azure / on-prem platforms (Front Door, WAF, Application Gateway, Spring Apps, Storage Account, Key Vault, PostgreSQL, Cosmos DB/MongoDB)
- 🔧 Industrialize CI/CD & GitOps (workflows, conventions, quality gates, approvals, environment promotions) + automation (Ansible, scripts)
- 📊 Structure observability (dashboards, alerting, log analysis)
- 🔄 Carry stacks (Spring Boot 2→3, Log4j→Logback), migrate (SVN→Git, on-prem→cloud), and ensure quality (SonarQube)
- 🧭 Lead & coach teams (technical referent, workshops, versioned docs, skill development)
- 🔎 Audit performance & architecture: mapping by reverse engineering, instrumentation, quick wins with demos and actionable reports
My daily convictions:
🧱 Infrastructure as Code • 🔁 GitOps • 👁️ Observability by design • 🛡️ Pragmatic Security • ✅ Measurable Quality • 📝 Useful Documentation • 🎓 Pedagogy & knowledge sharing
