Profile
DevOps Engineer with 6+ years of hands-on experience designing, automating, and supporting production and non-production infrastructure, Kubernetes platforms, CI/CD pipelines, monitoring, logging, and data services. Experienced with AWS, Terraform, Kubernetes, Helm, GitOps/ArgoCD, Kafka, PostgreSQL, MySQL, MongoDB, Redis, ClickHouse, ELK, Grafana, VictoriaMetrics, Bash, Python, and automation tooling. Strong in platform thinking, reducing manual operational effort through automation, improving reliability, and supporting engineering teams working with diverse application stacks.

Key Achievements
• Designed and implemented Parameter Checker — a Python-based service for monitoring and validating Apache Kafka / AWS MSK cluster parameters, topic configurations, and volume usage. Integrated with Prometheus, Slack, and AWS ECR, with support for alerting, reporting, versioning, and separate build pipelines for PROD and NON-PROD environments, reducing manual checks and improving operational control.
• Automated a wide range of manual operational tasks using Python, Bash, and Go, improving repeatability and reducing engineering overhead.
• Restored and standardized backup processes across core databases, refactored backup-related code, and improved maintainability and operational consistency.
• Optimized Elasticsearch cluster architecture for production and non-production environments, improving platform stability and manageability.
• Designed and implemented Elasticsearch and VictoriaMetrics clusters from the ground up.
• Actively contributed to the migration of services from Docker Compose to Kubernetes.
