GoUni
A university carpooling platform: rides, bookings, maps and real-time chat.
The problem
University mobility in Lima needs to coordinate trips, trust and communication between drivers and passengers.
What I built
A Spring Boot backend with DDD and JWT organized by contexts (IAM, carpooling and chat), a WebSocket chat service and an Angular frontend with Mapbox and STOMP.
Outcome
A university project covering the full journey of booking, simulated payment and communication between users.
Decisions that mattered
- 01
One context per responsibility
IAM, carpooling and chat are modeled with DDD, each with its own services, domain and repositories.
- 02
Real-time coordination
STOMP over WebSocket carries the conversation between participants; Mapbox adds geographic context to trips.
- 03
Continuous delivery
CI/CD on Azure Pipelines with Docker and Kubernetes, and tests with JUnit, Mockito and Selenium under TDD.
