Linda DN

About

DevSecOps/AWS infrastructure engineer at Madison Logic who owns a 15-account AWS footprint and treats nearly all AWS resources as code (Terraform/CloudFormation). Led a CI/CD platform migration (Bitbucket → GitLab + GitHub Actions) supporting WordPress and containerized microservices, improving release frequency to weekly/daily, and has hands-on production incident response experience on ECS Fargate using Datadog with fast rollback via immutable ECR tags and task definition revisions.

Key Strengths

• Migrated CI/CD from Bitbucket to GitLab and GitHub Actions for WordPress and containerized microservices
• Enabled faster release cadence (bi-weekly to weekly/daily) using trunk-based deployments across Stage/QA/Prod
• Strong pipeline security practices (masked/protected variables, AWS Secrets Manager, least-privilege IAM, environment approvals)
• Robust artifact/versioning and rollback design (immutable ECR tags, ECS task definition revisions, circuit breaker)
• Production incident troubleshooting using Datadog; identified memory leak causing 502s and executed rollback
• Owned AWS infrastructure across 15 accounts using Terraform and CloudFormation
• Mature IaC operations: reusable version-pinned modules, S3 state + DynamoDB locking, nightly drift detection with Slack alerts
• Safe rollout governance: PR review checklists, change windows for destructive changes, targeted applies for sequencing
