Senior DevOps Engineer | Cloud Azure · Kubernetes · IaC | Platform Engineering, FinOps & AI Infrastructure
I support tech teams in building and optimizing their cloud and on-premise infrastructures, with a constant focus on business impact, not just technical aspects.
With 4 years at Amadeus (hybrid environment, 1000+ VMs, 2000+ developers), I had the opportunity to work on high-value subjects: reducing cloud costs by 35% (achieved €400K/year), a 3-tier CI/CD architecture for a Kubernetes platform, distributed monitoring systems, and managing critical 24/7 on-call rotations.
In the last year, I took on the role of Tech Lead: guiding technical discussions with internal stakeholders, defining the long-term technical direction of the platform, and onboarding new team members.
What I bring:
- Technically driven decisions focused on measurable results (€, SLO, time-to-market)
- Ability to engage stakeholders: ADRs, presentations, cross-functional communication
- AI infrastructure expertise: LLM environment deployment, agentic-native platforms for Data/ML teams, integrating agents into DevOps workflows
- Rapid onboarding to new environments and domains
