Company decided to start the new data warehouse project, organizationally apart from the IT Department, under a brand new department of "Analysis and Data Management". So I got job among other five crew members, because: I have a good and diversity IT background; I was interested in data processing technologies. Responsibilities: - estimation of required capasities; - performing on-premise software installation and upgrade; - automation of routine system administration tasks; - code delivery automation; - fix related issues; - configuring of zabbix monitoring; - python programming; - backups. Achievements: - 3 envirements: sandbox, development, production; - deployment of 2 vertica clusters on 10 bare-metal servers, 5 of vertica databases; - 3 home-made docker compose apps (inspired by puckel) for Airflow Sandbox, Airflow Developmet, Airflow Production; - docker compose apps for additional services like jupyterhub, nginx, jenkins etc; - minio server pool of 3 bare-metal servers; - Ansible playboks for the Vertica and MinIO installations; - Operational Data Store on MinIO shared between environments; - python class for maintaining data between Stage on Vertica and Operational Data Store on MinIO; - Jenkins jobs and gitlab pipelines for the code delivery; - zabbix monitoring for the Vertica; - one more administrator/DevOps has been growed up.

It was short term and useful project. At the start: - Informatica Product 360 had stopped working several time per day and had not monitored. Responsibilities: - JVM(java Virtual Machine) tuning (JConsole, Java Mission Control); - setup of the logs transfer to Elastic (nxlog); - setup of the metricts transfer to NewRelic. Achievements: - performance of Informatica Product 360 had stabilized, performance metrics and logs became available for the staff.
