Jakarta EE · React · Microservicios · PostgreSQL · API Gateway
API gateway, Jakarta microservices, React SPA, event bus, PostgreSQL per service, centralized observability.
Clients call the gateway; the gateway routes to microservices; events to the bus for async flows; BFF aggregation when a unified view is needed.
We prioritized an API gateway and small services around business capabilities, with database-per-service where appropriate.
More team autonomy, incremental stack evolution, and better observability per service boundary.
