One of my hobby project architected and deployed on my Linux server. Built on clean architecture as 3 microservices, it features a .NET 8 WebAPI containerized with Docker. Supports distributed logging and tracing with Seq, metrics with Prometheus and Grafana. A Flutter app logs expenses and manages categories. The system uses RabbitMQ for messaging, Redis for caching, MongoDB for persistence, EF Core as ORM, Firebase for notifications, Azure EntraAD for auth & Blob storage for archrivals.

|---|---|---|---|
| Web | React | 18.2.0 | SPA |
| Mobile | Flutter | 3.22 | Android & iOS |
The project follows a microservices architecture with some components hosted in Azure.
