We have many projects and with very heterogeneous cloud infrastructures and services to manage deployed in Amazon Web Services (AWS) and Microsoft Azure: it is possible to manage them by using configuration management and Infrastructure as Code (IaC) tools as Ansible, Terraform and AWS CloudFormation. I designed and developed continuous deployment pipelines, integrating Azure Repos with Azure Pipelines, and GitLab with Jenkins. I also followed the integration and the management of all those tools necessary to guarantee the reliability, the safety, the security and the risk auditing of the data, application and infrastructure. I'm coding in the following languages: Bash, PowerShell, Python. Development Environment was composed by: - OS: Linux (CentOS, Ubuntu, Suse), Windows. - IDE: Visual Studio Code. - VCS: Git, GitLab. - AWS: EC2, IAM, VPC, Route 53, S3, Kinesis Streams, EKS, Lambda, WAF & Shield, ElastiCache for Redis, Glue e Athena, Organizations. - Monitoring Systems: Nagios, Nessus, Tenable, Grafana, Prometheus, AWS CloudWatch, AWS CloudTrail. - ELK stack: Logstash, ElasticSearch and Kibana. - IaC: Terraform, AWS CloudFormation, Ansible. - Orchestration: Kubernetes - Linux Services: Apache, Nginx - CI/CD: Jenkins, Azure DevOps
