з 05.2025 по нині (9 місяців)
AI startup Metrix, Інші країни (IT)

- Designed and maintained infrastructure for an AI startup, including VPS setup, virtualization, and Kubernetes cluster management.
- Implemented PostgreSQL WAL streaming for reliable replication and disaster recovery.
- Developed custom agents and RPC tools to streamline communication between distributed services.
- Engineered solutions that significantly improved product performance and scalability, ensuring faster response times and higher throughput.
- Established and enforced security best practices, including access control, firewall segmentation, and credential management.
- Collaborated effectively within a distributed international team, ensuring smooth deployment processes and operational handoffs across multiple time zones.
- Automated CI/CD pipelines and monitoring workflows to increase reliability and reduce manual overhead.
- Documented runbooks and operational guidelines to support reproducibility and transparent diagnostics.
- Architected and deployed a complete Data Warehouse (DWH) ecosystem, integrating ingestion, orchestration, storage, and visualization layers.
- Data Ingestion Layer: Configured Kafka + Zookeeper for real-time event streaming and CDC pipelines, ensuring reliable buffering and high-throughput data capture.
- Orchestration Layer: Implemented Apache Airflow with PostgreSQL (metadata) and Redis (Celery broker), managing ETL/ELT workflows, DAG scheduling, retries, and error handling.
- Storage Layer:
- Designed MinIO (S3-compatible) as a raw data lake, backup repository, and archival solution.
- Optimized ClickHouse OLAP cluster for analytical queries, time-series data, and reporting dashboards.
- Visualization Layer: Integrated Grafana for system monitoring and alerting, and Metabase for BI analytics and self-service reporting.
- Networking & Security:
- Built secure Docker networks with controlled port mappings for inter-service communication.
- Applied RBAC, TLS/SSL, secrets management, encryption at rest, audit logging, and VPN access for production-grade security.
- Scalability & High Availability:
- Configured horizontal scaling of Airflow workers and Kafka brokers.
- Designed ClickHouse replication/sharding, PostgreSQL master-slave replication, Redis Sentinel/Cluster, and MinIO distributed mode.
- Monitoring & Metrics: Established observability for system, application, and business metrics (CPU/memory, Kafka lag, DAG success rates, query performance, SLA compliance).
- Disaster Recovery: Automated backup strategies for Docker volumes, configurations, and ClickHouse datasets, with documented recovery procedures.
- Cost Optimization: Applied compression, retention policies, lifecycle rules, and log cleanup to reduce infrastructure costs while maintaining performance.
