AWS Service Integration: Select and integrate AWS services based on application needs, such as EC2/ECS/EKS for compute, S3 for storage, RDS for databases, API Gateway for APIs, and Lambda for event-driven processing.
Implement basic disaster recovery mechanisms using AWS-native features.
Containerization & DevOps Automation: Containerize legacy and modernized applications using Docker, and deploy them to AWS services like ECS or EKS.
Use IaC tools such as AWS CloudFormation, SAM, or Terraform to automate environment setup, ensure consistent deployments, and support CI/CD pipelines.
Governance, Standards & Cost Awareness: Follow established cloud guidelines, coding standards, and architectural patterns approved by leadership.
Collaboration & Communication: Work closely with project leadership, SCRUM teams, and cross-functional stakeholders.
