About Marco

DevOps specialist with a challenge-oriented mindset, my mission is to transform technical challenges into stable, secure, and scalable operational solutions. I bring over 12 years of experience in reducing the adoption curve of new technologies andtime-to-market.

My expertise extends across the entire development and operations lifecycle, mastering a high-performance technology stack:
  • 🏆 **Containers and Orchestration**: Leadership in designing, deploying, and managing scalable environments with Kubernetes, Docker, OpenShift, and ECS.
  • 🌐 Cloud Infrastructure:Extensive experience in designing cloud infrastructure on AWS, Azure, and GCP, with Infrastructure as Code provisioning.
  • ⚙️ **Automation and CI/CD**: Implementation of robust Integration and Deployment pipelines in GitLab CI, GitHub Workflows, and Jenkins.
  • 🛠️ Software Engineering / Operations:Version Control (Git), Observability, and Configuration Management.
  • 🔒 Networking and Security:High availability configuration, network segmentation, and access management.
My methodology translates into tangible results. With personal automation scripts and rigorous implementation of best practices, I have consistently achieved up to a 20% reduction in deployment time and cost efficiency.

My work philosophy is based on continuous improvement and sustainability. I integrate security from the early stages of design (**Security-by-Design**). A fundamental pillar of my service is knowledge transfer; I document every process and train internal teams.

My goal is to connect with leaders, companies, and fellow engineers. I am open to exchanging knowledge, discussing complex systems, or exploring the latest innovations. If you are looking for a strategic perspective on DevOps or have challenges in implementing automation and CI/CD, I invite you to connect.
