👋 Hello, I'm Oscar Macias 😎✨

🛠️ As a Site Reliability Engineer (SRE), which is just a fancy way of saying I make sure things don’t break (🤞too often). With over twenty-two years of experience keeping the infrastructure ⚙️, automation 🤖, and observability 👀 train on the rails 🚂, my mission is to help teams deploy 🚀 and maintain rock-solid 💪 applications in production—because nothing says excitement like a system that just works 🎉.
