  • Deep understanding of hosting static sites and SPAs using S3 and CloudFront, and managing compute/networking via Lambda, API Gateway, and VPC.
  • Expertise in writing modular, reusable HCL code
  • Experience managing state files (remote state locking with DynamoDB/S3) and creating custom modules
  • Creating complex workflows (YAML) for linting, testing, building Docker containers (if applicable), and deploying infrastructure changes
  • Implementing strategies like Blue/Green deployments or Canary releases for frontend applications
  • Integrating observability tools (CloudWatch, Datadog, or Sentry) to track application health and errors.
Benefits
