About Me
Hi there, it's nice to see you here! I'm Fernando, a SENIOR INFRA, SYSADMIN, CLOUD and DEVOPS ENGINEER with 30+ years of experience in IT. Yes, I started my journey really young, about 13 years old, learning about DOS 6.22, Windows 3.11, WordStar, Clipper and DBASE (some old stuff).
I am self-motivated and a fast learner with a strong professional background in both the public and private sectors. My focus is always on security and best practices to achieve high availability of systems and services.
For the last 24 years I have been working inside on-premise Data Centers and I can say I always try to bring the most efficient solutions, that is why I have been prioritizing to implant and manage so many open-source solutions, and when is not possible, I evaluate the paid solutions with the pros and cons and their impact in the business. So, when a decision it is not at my reach, I can provide assuredness to my superiors and they can do the best decision for the company. Due my long-time experience in IT, I can assure I have a combination of technical skills and business knowledge that work as an advantage for me and the company, affording me the ability to preview the impact of choices and decisions about IT in the whole business scenario.
In the last 7 years my focus has changed to the Cloud and Devops areas due to the demands of my last job and with my long on-premises experience this change was very smooth and I also discovered a new love. Due to this new love, I took dozens of certifications and training in Cloud, Devops, IAC, CI/CD and much more.

Containers and Orchestration: Rancher and Kubernetes (the challenge to run Kubernetes in a floating Data Center – aka: inside a Cruise Ship);
-
Source Control Management (SCM): GITHUB and GITLAB;
-
Infrastructure as a Code (IaC): Terraform and Atlantis;
-
Configuration management: Ansible and AWX;
-
CICD: Jenkins, Rundeck, AzureDevops, GitLab CI;
-
Windows and Linux servers.
