I’m Antonio Marchi, a Site Reliability Engineer with a focus on ML Ops and on-prem platform engineering. I’ve led migrations across cloud and on-prem, cut millions of infra spend, and designed reusable blueprints by pooling knowledge from senior engineers across London and NYC. My experience spans public cloud and on-prem environments, with a recent emphasis on low-latency systems and end-to-end data center management. I even built a data center in my basement to run ML/AI projects that inform investment decisions (my geeky gambling hobby). I’ve led CI/CD redesigns, telemetry adoption, and production readiness across distributed teams, and I’ve worked in London and NYC to support 80+ engineers building proprietary trading platforms. I enjoy hands-on engineering and collaboration with other seasoned engineers to deliver reliable, scalable platforms.…I’m Antonio Marchi, a Site Reliability Engineer with a focus on ML Ops and on-prem platform engineering.
