Golang Backeng Developer
VK CLOUD
2024 - 2025
Developed SLI monitoring based on RED metrics, invented an SLO computing method using a WCI that factors in performance and availability metrics. This innovation boosted issue detection accuracy by 27.1%. Influenced team load-testing practices by troubleshooting a production IAM outage triggered by 439+ non-recoverable goroutines and engineering Kubernetes manifests for load testing, which guided fixes that boosted throughput from 3K RPS to 14K RPS. Implemented a concurrent Kubernetes CronJob in Golang to reliably produce sensitive billing data (8M+ messages daily) into a Kafka cluster, achieving 99.9% data integrity and a 45.7% boost in producer speed. Tech: Golang, Kube, Docker, Baremetal, Linux, Postgres, Kafka, ELK, Grafana, Prometheus, Gitlab
