Description

I help companies design, improve and troubleshoot reliable cloud platforms, with a focus on AWS, DevOps, Terraform, cloud networking, CI/CD, observability and infrastructure security.

I bring senior platform engineering experience from production environments where reliability, scalability, cost control and clear operational ownership matter. I’m especially useful when teams need to stabilize messy infrastructure, improve deployment pipelines, review AWS architecture, troubleshoot networking/DNS/TLS issues, modernize platform practices or make systems easier to operate.

My background combines hands-on engineering with technical leadership, so I can both implement solutions and help teams make better architectural decisions. I have experience with AWS, Kubernetes/EKS, Cloudflare, databases, monitoring, incident analysis, automation and platform reliability.

Typical projects I can help with include cloud architecture reviews, DevOps automation, Terraform improvements, CI/CD optimization, AWS cost and reliability audits, observability setup, infrastructure troubleshooting and security-minded platform improvements.

Peer recommendations and full professional background are also available on LinkedIn under my full name: Guillermo Casanova Rizo.
