System Architecture & Technical Execution:
• Meta WhatsApp Cloud API Webhook Pipeline: Engineered an event-driven Node.js webhook engine that parses incoming customer order payloads, executes automated response trees, and issues interactive order confirmations with zero manual latency.
• Deterministic Logistics Routing Engine: Developed an automated dispatch verification module that cross-references customer pincodes against regional transit cargo hubs to determine shipment eligibility and direct hub routing automatically.
• Real-Time Operations SPA Dashboard: Built a lightweight, secure single-page administrative dashboard providing live order tracking, customer dispatch states, and instant inventory toggles backed by persistent relational storage (SQLite).
• Secure API & State Integrity: Configured resilient error handling, payload validation, and webhook security to ensure zero dropped orders or race conditions during dispatch spikes.
