DevOps
A CI/CD platform for four containerised Lambda microservices, built inside a private VPC because managed CI/CD services are unavailable in the lab. GitHub Actions run on self-hosted EC2 runners in private subnets, images go to ECR, REST and WebSocket API Gateways expose the functions, and CloudWatch, VPC Flow Logs, Secrets Manager, and Cognito cover observability and security.
Data
A five-layer data platform: CSV batches land in S3 and user events stream through Kinesis; Glue, EMR, Step Functions, and EventBridge transform and orchestrate; Redshift, DynamoDB, and S3 store history, real-time metrics, and the lake; Lambda behind API Gateway serves five endpoints protected by WAF and API keys; a dashboard on Amplify shows GMV, sales, funnel, and ML segments.
