DevOps / AWS / Terraform / CI/CD

Yevhenii Puhachov Senior DevOps Engineer

Cloud, IaC, CI/CD pipelines, migration to AWS, hybrid infrastructure. Monitoring and logging, automation, security, collaboration, and communication—DevOps best practices in complex environments.

About me

Senior DevOps Engineer with end-to-end ownership of infrastructure automation, cloud operations, and delivery pipelines. I architect and maintain infrastructure as code (Terraform, Ansible, Chef), build and optimize CI/CD with Jenkins and GitHub Actions, and run containerized and serverless workloads on AWS—including ECS Fargate and Lambda. I automate operations with Bash and Python and use monitoring and logging stacks (Datadog, ELK, Prometheus) for observability and incident response. I hold multiple AWS certifications at the Professional level (Solutions Architect, DevOps Engineer) and HashiCorp Terraform Associate. My focus is on modernizing legacy infrastructure, strengthening reliability and security, and leading DevOps and platform-engineering initiatives in complex, cross-functional organizations.
