* Note on engineering benchmarks: Latency measurements reflect internal benchmark testing environments under controlled loads with optimized B-Tree database indexes and API response caching. Actual production performance varies based on hardware provisioning, network conditions, payload size, and concurrent system load.
Challenge & Bottleneck
A modern loan origination platform required a cohesive digital ecosystem: a mobile-first borrower application flow, instant policy checks, Document AI statement OCR, executive lead routing, and an administrative review console.

Key Engineering Decisions & Rationale
Decoupled Next.js & Fastify Architecture
Rationale: Decoupling allowed edge hosting for the borrower frontend while the Fastify backend scaled independently for heavy OCR processing.
Document AI Pipeline
Rationale: Replacing manual underwriter data entry with neural OCR reduced average document ingestion time significantly.
