About Alejandro

Senior DevOps Engineer | Cloud Azure · Kubernetes · IaC | Platform Engineering, FinOps & Infrastructure AI

I accompany tech teams in building and optimizing their cloud and on-premise infrastructures, with a constant focus on business impact, not just technical.

In the last 4 years at Amadeus (hybrid environment, 1000+ VMs, 2000+ developers), I have worked on high-value-added projects: 35% cloud cost reduction (€400K/year realized), 3-tier CI/CD architecture for Kubernetes platform, distributed monitoring systems, and management of critical 24/7 on-call rotations.

During the last year, I took on the role of Tech Lead: directing technical discussions with stakeholders, defining the platform's long-term technical directions, and onboarding new team members.

What I bring:
  • Measurable results-oriented technical decisions (€, SLO, time-to-market)
  • Ability to align stakeholders: ADRs, presentations, cross-functional communication
  • Sensitivity in AI infrastructure: LLM environment deployment, agentic-native platforms for Data/ML teams, agent integration in DevOps workflows
  • Fast onboarding in new environments and domains
Main stack: Azure (AZ-104 / AZ-500 / AZ-305) · Kubernetes / OpenShift · Terraform · Ansible · Jenkins / GitHub Actions / ArgoCD · Prometheus / Grafana · Go · Python · SAFe® 5 Certified

Expert in improving developer productivity (DevEx), FinOps, cloud migration, infrastructure security, and AI / GenAI infrastructure.
