Cloud-native AWS platform — discovery to production

Problem

Product teams needed a production-ready AWS foundation: secure networking, repeatable environments, automated delivery, and clear operational ownership — without weeks of manual setup per environment.

Solution

• Multi-AZ architectures targeting >99.95% availability, combining microservices, serverless (Lambda, API Gateway, EventBridge, DynamoDB, S3), and container workloads on ECS/Fargate
• Infrastructure automation with Terraform and AWS CDK (Python/TypeScript), reusable modules/constructs, and CI/CD promotion across environments
• Security baseline: least-privilege IAM, WAF, CloudTrail, Config, Security Hub, encryption, and secrets management
• Observability and production readiness: CloudWatch dashboards/alarms, automated operational responses, tagging and cost dashboards

Results

• Environment provisioning reduced from approximately five days to one hour
• Standardized architecture patterns and mentoring that improved delivery consistency
• Continuous FinOps visibility (unused resource detection, tagging standards)
