Architecture decisions that matter
Modular Monolith over Microservices
Clear domain boundaries within a single deployable unit. The right trade-off for a regulated product where consistency, transaction safety and operational simplicity matter more than independent scaling.
Ports and Adapters over Direct Integration
All external systems are accessed through port interfaces. This isolates the domain from infrastructure concerns and makes core banking, payment rail or compliance provider swaps achievable without domain model changes.
PostgreSQL-First over Multi-Database
A single PostgreSQL instance with logical separation per concern. Simpler operations, easier backups, ACID guarantees across domains and proven reliability at financial-grade workloads.
Sync over Async by Default
Spring MVC with synchronous request handling for predictability and debuggability. Async patterns introduced only where explicitly needed — payment rail callbacks, event streaming and background processing.
