PROFILE
Liya Katz
Liyak worked extensively on the comet-ml/opik repository, delivering robust infrastructure and deployment automation for a cloud-native backend platform. Over 18 months, Liyak engineered Helm-based Kubernetes deployments, automated CI/CD pipelines with GitHub Actions, and enhanced observability and security through Docker, Nginx, and OpenTelemetry integrations. Their work included implementing multi-architecture Docker builds, secure secret management, and modular Helm charts supporting ClickHouse, MySQL, and MinIO. Using Python and TypeScript, Liyak improved release reliability, streamlined developer onboarding, and enabled flexible, reproducible deployments. The depth of engineering addressed operational risks, reduced manual intervention, and established a maintainable, scalable foundation for production and self-hosted environments.
