PROFILE
Vladimir Barinov
Over six months, contributed to DayMarket/infra-docker by building and maintaining containerized infrastructure for data and workflow platforms. Delivered features such as Trino and Hive Metastore image upgrades, Airflow dependency alignment, and a containerized JMX Exporter for improved observability. Developed a Keycloak to Apache Ranger user synchronization service, implementing robust data ingestion, validation, and group-based provisioning with enhanced logging. Automated CI/CD pipelines using GitHub Actions and Docker, focusing on secure publishing and reproducible builds. Used Python, Bash, and YAML to address deployment stability, security, and maintainability, consistently improving runtime reliability and supporting faster, auditable delivery cycles across environments.
