Problem shape
Tax workflows fail when operational reality is treated as an edge case. Documents arrive incomplete, connectivity drops, and audit history still has to survive every correction, retry, and handoff.
Approach
TaxBridge separates OCR intake from the computation engine so the document pipeline can degrade gracefully without weakening rule enforcement. The compute layer uses Java 17 and Spring Boot 3 because jurisdiction logic benefits from compile-time validation, while Postgres Row-Level Security and append-only audit events keep tenant boundaries and regulator-facing traceability anchored at the database layer.
Delivery signal
The system demonstrates offline-first thinking, compliance-aware backend design, and architecture choices shaped by reliability and auditability rather than by framework convenience.
