Designed and implemented the migration of project services from the data center "Hetzner" to the GCP cloud

Designed and configured GCP infrastructure

All the infrastructure was described by me in Terraform.

Software in K8s clusters is deployed using argocd, (and accordingly the entire cluster configuration is stored in git and can be easily redeployed in a new cluster)

Implemented and configured GitHub Actions CI - CD (build, testing end deploy service to GKS)

CI-CD: - GitHub Actions
Monitoring: - Prometheus +Grafana+Loki
Automation: - Terraform

Designed and implemented the migration of project services from the data center to the AWS cloud

Configured and integrated the Prometheus + Grafana + Loki monitoring and log collection system

Implemented and configured GitLab CI - CD (build, testing end deploy service to EKS)

Built the infrastructure of the company's projects in Kubernetes in Google Cloud Platform.

Configured the Docker Swarm cluster and service deployment in the cluster

CI-CD: - Azure DevOps

Monitoring: - Prometheus +Grafana + ELK

Automation: - Terraform, Ansible

Built from scratch the infrastructure of all the company's projects in Kubernetes in Google Cloud Platform.

CI/CD - Git-Lab

Monitoring - Prometheus +Grafana + Loki

Automation - Terraform
