A light touch in C# for one integration microservice may pop up, so familiarity there is helpful. Stack glue we’re already using (and that you should feel comfortable with): Docker, Terraform, PostgreSQL, Redis and basic AWS/Azure monitoring suites. Acceptance criteria 1. All Python services lint-clean, fully unit-tested, and containerised. 2. CI/CD pipeline runs on every PR and deploys to staging then production with zero-downtime. 3.
