Summary

Rockstar🎓
Top SchoolAndrei Afoninskii is an Observability Senior SRE based in Amsterdam with 12 years of experience building large-scale, resilient infrastructure and telemetry platforms for high-throughput, multi-cloud environments. He has led observability and Kubernetes initiatives at Booking.com and Mambu, architecting end-to-end stacks (Grafana, Mimir/VictoriaMetrics, Loki, Tempo, OpenTelemetry) and custom Go services to reduce MTTR and surface actionable SLO-driven insights. Comfortable across bare-metal, AWS, Kafka, and Lambda, he combines hands-on engineering—writing operators, custom instrumentation, and telemetry pipelines—with IaC and automation using Terraform, Ansible, ArgoCD and GitOps. He’s also mentored teams and advocated standardized instrumentation through workshops, translating platform complexity into clear operational practices. Notably, he has scaled and operated thousands of Kubernetes nodes and built internal observability platforms that unify logs, metrics and traces into single-pane troubleshooting. His background in cryptography and early roles in security and high-performance backend systems brings a pragmatic focus on reliability, performance and measurable SLAs.
