SpendBearBackEnd
A production-grade backend API for personal finance management built with C# that demonstrates modular monolith architecture, domain-driven design, and reliable event processing. The system isolates six business domains (Identity, Spending, Budgets, Analytics, Notifications, StatementImport) with strict layer separation and communicates between modules exclusively through domain events, enabling decoupled domain logic without distributed system complexity. It implements an outbox pattern for atomic event delivery, CQRS-style command/query organization, and Auth0-based authentication.
SpendBear is a personal finance management API built as a modular monolith with six domain modules that communicate exclusively through domain events and an outbox pattern for reliable event delivery. The project demonstrates production-grade backend engineering practices including CQRS, domain-driven design, Auth0 integration, and comprehensive CI/CD with Azure DevOps.
- ✓Excellent architectural documentation explaining design decisions like avoiding MediatR and choosing modular monolith over microservices
- ✓Robust outbox pattern implementation for reliable event processing with atomic writes to eliminate dual-write problems
- ✓Comprehensive CI/CD pipeline with proper migration handling, smoke tests, and staging/production deployment gates
- →Add concrete code examples and API endpoint samples to the README to demonstrate actual usage patterns
- →Include performance benchmarks or load testing results to validate the production-ready claims
