Problem
Application services need to hand off email delivery without each caller managing mail transport and templates.
My contribution
Worked on RabbitMQ connection configuration, email consumer and delivery handling, and Docker setup. This was a shared service; my contributions focused on integration and delivery behavior.
Engineering decisions
- RabbitMQ separates notification producers from the email consumer.
- Email templates and delivery handling live in the notification service.
- Connection configuration and error handling make delivery failures easier to investigate.
- Docker setup supports running the service consistently.
Outcome
Contributed the messaging connection setup and email error handling used by the service, plus its container configuration.
What I learned
A notification path needs explicit connection and delivery error handling, not only a working email template.
