About Me

Section titled “About Me”

I’m David Dominguez, a Senior DevOps and Site Reliability Engineer with 6+ years of professional experience designing, automating, migrating, and operating production infrastructure and cloud-native platforms.

My background spans Cloud Engineering, Site Reliability Engineering, Platform Engineering, Infrastructure as Code, Kubernetes, CI/CD, GitOps, Observability, Automation — and, increasingly, AI Engineering and Agentic Operations. I’ve worked across Google Cloud Platform, AWS, and Microsoft Azure, building reliable, scalable infrastructure, automating operational processes, improving developer workflows, and implementing observability and reliability practices for production systems.

My current direction focuses on combining traditional DevOps and SRE practices with LLMs, AI agents, RAG, MCP, and workflow automation — exploring the evolution from Infrastructure as Code toward intelligent, agent-driven operations.
