Senior DevOps & Cloud Engineer
Seven years of building AWS and Azure platforms that are automated, secure, and easy to observe.
About
I'm a DevOps and cloud engineer with more than seven years of experience designing, automating, and running enterprise infrastructure on AWS and Azure. My daily work covers Kubernetes, Terraform, GitLab CI/CD, Jenkins, Linux, Python, and Bash.
I like platforms that are secure by default and easy to see into: DevSecOps pipelines, access control with SAML SSO and RBAC, reliable backup and recovery, and centralized logging that makes problems quick to find.
Highlights
- Centralized log analytics for 3M+ CloudWatch events with Amazon OpenSearch
- Lifecycle management and reporting for 100+ user accounts, automated with Python
- Enterprise authentication and authorization with SAML SSO and RBAC
- SAST, DAST, dependency, and container scanning built into GitLab CI/CD
- On-premises workloads migrated to AWS and Azure
- Infrastructure, deployment, backup, and notification workflows automated with Terraform, Python, and Bash
