About Marco Agüero
Most systems don’t fail because of bugs.They fail because reliability decisions were made too late.I build systems that stay up while everything changes.Over 20+ years operating distributed systems, with recent work focused on AI-assisted operations: agents that reason over telemetry, accelerate incident response, and reduce human dependency in production systems.I work at the intersection of reliability, observability, and intelligent automation, where data becomes decisions.What I do - Build SRE practices from zero to scale- Design AI agents for incident triage, causality, and remediation- Turn telemetry into operational signals, not noise- Reduce MTTR, cognitive load, and on-call fatigue- Treat reliability as a product and a competitive advantageSystems & Stack - OpenTelemetry pipelines & custom collectors · Distributed tracing at scale- Kubernetes (EKS) · AWS multi-account architectures- Infrastructure as Code (Terraform) · GitLab CI/CDHigh-throughput data systems · Event-driven architectures- Go & Python for production automationI value leverage, correctness, and systems that age well.
