Building a $300k AI-Orchestrated POS Telemetry Pipeline for Multi-National Retail Footprints

Description and use

An AI‑driven POS telemetry pipeline was built for a multinational retail chain, automating data capture, cleaning, and real‑time analytics to enable precise marketing ROI attribution.

Problem

Retail chains lack integrated data linking field marketing efforts to in-store transaction telemetry, causing attribution gaps and manual data cleaning.

Outcome

Unified cross‑border POS data, automated 100% data cleansing, and enabled precise ARPU attribution, achieving a $300k ROI for the client.

Workflow

• Deploy React.js front‑end on in‑store tablets via Vercel edge network
• Expose GraphQL API on Node.js runtime
• Integrate OpenAI GPT via LangChain for data cleaning and PII sanitization
• Store cleaned JSON payloads in PostgreSQL
• Automate real‑time customer segmentation and ARPU calculation
• Deliver insights to client IT administrators

Evidence

100% Data Cleansing Automation: Replaced manual administrative entry with automated LangChain/GPT workflows, dropping data pipeline ingestion error rates to near zero.
