Expert-level DevOps/SRE & RHCE
To the Hiring Manager,
As a Red Hat Certified Engineer with over 20 years of experience architecting and managing large-scale GNU/Linux environments, I have a proven track record of delivering highly available, cost-effective, and scalable infrastructure solutions. My expertise in automation, virtualization, and resilient system design has enabled me to achieve significant cost reductions and massive capacity scaling for clients.
My background is defined by leading complex infrastructure projects from concept to completion. For the Mexican Federal Government, I have deployed a highly available OpenStack private cloud on an OpenShift foundation and, most recently, consulted on the migration of ~4,500 legacy instances from RHOSP 16.2 to RHOSO 18, utilizing custom scripting to reduce migration labor hours by 80% and transfer core resources in minutes. In commercial roles, I engineered a cloud migration for Grupo QUID that reduced operational costs by 90% while scaling capacity by 3000%, solo-architected a high-availability OpenStack control plane on Google Cloud Platform in under three weeks (saving $80k+ in team resource fees), and have managed GCP infrastructure for AdvantageMLS since 2018, reducing monthly spend by 35% ($45k+ annualized savings) while maintaining a perfect zero-breach record.
I am driven by a philosophy of robust automation, comprehensive documentation, and relentless efficiency. My expert-level skills across the modern infrastructure stack—from Kubernetes and Ceph to Ansible and Terraform—are built upon deep, foundational expertise in the Linux kernel and distributions like RHEL, CentOS Stream, and Gentoo. As a specialist in creating comprehensive documentation using Sphinx, I ensure projects are maintainable and knowledge is transferable.
I am confident that my skills and experience can deliver significant value to your organization, and I look forward to discussing your needs in more detail.
Sincerely,
