Cover Letter: René Bon Ćirić

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 allowed me to achieve significant cost reductions and massive capacity scaling for my clients.

My background is defined by leading complex infrastructure projects from concept to completion. For the Mexican Federal Government, I was instrumental in deploying a highly available OpenStack private cloud on an OpenShift foundation. In a commercial engagement with Grupo QUID, I engineered a cloud migration that resulted in a 90% reduction in operational costs while simultaneously scaling system capacity by 3000%.

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 a 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 that 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,
