- writing ansible roles- deploy services (gitlab ci, ansible)- deployment of infrastructure for projects from scratch (Apache Kafka, Postgresql, Redis, Elasticsearch)- application of diverse solutions to problems- monitoring (prometheus, grafana)- logging (EFK, ELC)- support for ci/cd pipelines- consulting developers in projects- solving network problemsMost of the time I worked with docker, with Kubernetes less (mostly used in production environments).

- Writing ansible roles- Deploy product services (ansible awx)- support for the continuous operation of the project infrastructure (each service is clustered)- monitoring (collecting product metrics from environments + setting up dashboards in Grafana)- logging (graylog)
