• Modular Business Logic: Isolated monolithic contract and payment services into clean, reusable FastAPI micro-modules.
• Role-Based Access Control (RBAC): Built declarative middleware securing sensitive payment authorizations and inventory adjustments.
• Reporting Pipeline Automation: Engineered background processes to reconcile inventory transactions against financial ledger entries automatically.

Measurable Business ROI

• 50% Reduction in average API response times across core accounting and inventory endpoints.
• Zero Reporting Timeouts: Management dashboards and monthly tax reports generated in real time without crashing workers.
• 100% Audit Readiness: Clear permission trails on all high-value contract and inventory actions.
