Summary
🤩
Rockstar🎓
Top SchoolMarco Pracucci is a Principal Software Engineer II with 14 years of experience building and operating large-scale, cloud-native observability systems, currently leading Mimir development at Grafana Labs. A co-founder and former CTO of Spreaker, he scaled a podcasting platform to over 100M monthly users and later led SRE efforts to productionize Kubernetes-based infrastructure and CI/CD at Voxnest. Marco blends hands-on backend engineering with platform leadership—shipping reliability, partitioning fixes, and query-consistency improvements across high-profile OSS projects like Grafana Mimir, Prometheus, Thanos and Loki. His open-source work focuses on robustness of ingestion and storage pipelines (notably fixing Kafka partial-failure data loss and TSDB memory optimizations) and practical observability improvements surfaced in dashboards and metrics. Based in Italy and academically trained at the University of Bologna with top honors, he prefers Twitter over LinkedIn for quick contact and keeps a low public profile despite a deep impact on monitoring ecosystems.
