01 — Problem

The Challenge

Teams struggled with scattered receipt records and delayed reconciliation.

02 — Solution

Solution Approach

Implemented a full-stack workflow system with API automation and auditability.

03 — Architecture

Architecture Decisions

Containerized web stack with API-first services, asynchronous document processing workers, and a reporting layer optimized for month-end close cycles.

  • API-first services so the web client, integrations, and reporting tools share one contract.
  • Asynchronous OCR workers isolate document processing from request latency.
  • Role-based review queues route exceptions instead of blocking the happy path.
