À propos de Antonio

AVAILABLE FOR IMMEDIATE START (On-site Zug/Zurich commute area or Hybrid)

With over 20 years of experience in IT, I stabilize, automate, and optimize Cloud environments. I am a Senior Cloud Architect & Engineer specializing in turning complex, high-cost, or unstable infrastructures into high-performance platforms.

If your team is facing a project bottleneck, a skyrocketing cloud bill, or a complex migration that needs an expert to hit the ground, I am ready to help. No hand-holding required.

What I bring to your project:

Cloud Engineering: Deep expertise in AWS, and GCP knowledge.

Infrastructure as Code (IaC): Expertise in enterprise-scale Terraform, Ansible, and CloudFormation.

Container orchestrators: Designing and scaling production-ready clusters.

FinOps & Cost Control: Proven track record of auditing and slashing unnecessary cloud spend.

CI/CD & DevOps: Building robust pipelines that allow engineering teams to move faster while improving governance.

Security & Compliance: Hardening infrastructures and workloads to meet regulatory standards.

Why hire me for your next contract?
I am a "plug-and-play" consultant. I understand the intersection of Architecture, Security, and Engineering, and I speak the language of business stakeholders. I lived the evolution of IT from on-premise, MVC to Cloud-native, event-driven, and I use that 20-year perspective to avoid costly architectural mistakes.

Project Info:

Status: Immediately Available.

Role Prefs: Contract / Freelance / Interim.

Location: Based in Switzerland (Zug/Zurich/Ticino commuter).
