   • Carried out the migration of a warehouse WMS backend from Express to NestJS (strict TypeScript), achieving verified functional parity with the legacy system through a contract-test suite that compares both APIs.
   • Integrated the WMS with the ERP across receiving, cycle counting, inventory, transfers, and scrap, keeping warehouse operations in sync with response validation and typed failure handling.
   • Made the platform production-ready: PIN-based JWT authentication with role-based access, closure of exposed system routes, and reliability controls (30 s query timeout, DB keepalive, PM2), validated by integration, e2e, and equivalence tests.
   • Delivered an Android PDA app (React/Vite + Capacitor) with 17 operational screens, barcode scanning, and 3-language support (ES/EN/KO), featuring a redesigned, AA-accessible UI with light/dark mode for floor operations.
