Saga choreography pattern for managing distributed transactions across microservices using asynchronous events. Each service participates in the saga by emitting and responding to domain events, eliminating a central orchestrator. The project includes multiple cooperating services, event definitions, and examples of compensation flows to handle failures in event sequences.

Saga pattern with an orchestrator for managing long‑running distributed transactions. A central coordinator (orchestrator) directs microservices through a series of steps and compensation actions when necessary. It’s a learning lab designed to contrast with event‑driven choreography, show transaction boundaries, and explore rollback strategies in distributed systems.

This is my mobile application demo "Super GT Fan Tracker App". It consists of a cloud deployed back-end and an Android mobile application front-end. The back-end is designed to be run in a Ubuntu Server 25.04 container or deployed through a Docker container, making data available via API endpoints. The front-end is meant to be installed on an Android device and will regularly make API requests to the back-end to receive updated information about races, teams, drivers, and current standings.
