How I build — deploy to response

A git push is built, tested and shipped to ECS; then one request travels end to end, with a trace and live log on the same clock.

CI/CD deploy with GitHub Actions, Docker, ECR and ECS, then a request through CloudFront, API Gateway, Keycloak, Spring Boot, PostgreSQL and Kafka
