About Me

gabriel@devops:~ $ whoami

$ cat about.txt

Cloud & DevOps Engineer who lives in the terminal and builds infrastructure that lasts. I specialize in AWS, Kubernetes, Infrastructure as Code, observability, and automation — turning complex systems into environments that are reliable, secure, and easier to operate.

My work focuses on the infrastructure layer modern applications depend on: cloud architecture, compute platforms, deployment systems, monitoring, and incident response. Recently, I built KubeGuardian, a Kubernetes incident response platform designed to improve diagnostics, visibility, and controlled remediation during failures.

I'm passionate about the intersection of DevOps and AI, but I believe the best systems start with strong infrastructure, clear observability, and dependable operations.

Featured Projects

Secure Software Supply Chain Pipeline

Built a production-grade supply chain security pipeline on AWS EKS where every image must prove its identity before it runs. GitHub Actions signs images with Cosign, generates CycloneDX SBOMs with Syft, scans for CVEs with Grype, and attaches SLSA Level 2 provenance — all enforced at admission by Kyverno.
