Denis K.

Platform and reliability engineer with 10+ years of experience designing, building, and operating production infrastructure across e-commerce, AdTech, EdTech, and Web3 domains. Deep hands-on expertise across the full platform stack: container orchestration (Kubernetes, Swarm), IaC (Terraform, Ansible), CI/CD (GitHub Actions, GitLab CI), and observability (Prometheus, Grafana, ELK, OpenTelemetry). Experienced in leading SRE and DevOps functions at scale — including a 25-person department at a top-10 Russian foodtech company — while staying close to the technical work. Built and operated event-driven data pipelines on Kafka and NATS, managed Postgres and ClickHouse at production scale, and built internal developer platforms that reduced deployment time and incident frequency by 30–50%. I approach reliability as a product: SLOs, incident response, and operational ergonomics are first-class concerns, not afterthoughts.
