AWS LambdaAPI GatewayDynamoDBPythonZPLCSV Pipelines
Overview
A production-grade QR badge system built to generate unique employee QR codes, track scans across devices, and support high-volume physical label printing. The system integrates a serverless AWS backend with printer-native ZPL generation for reliable hardware output.
Problem
Needed a reliable way to generate and track employee QR badges while integrating with thermal printer hardware and avoiding brittle PDF-based workflows.
Solution
Built a serverless AWS system with native ZPL output to bypass PDF scaling issues and ensure consistent printing across Zebra devices.
Results
- Reliable QR scanning across devices
- Accurate scan metrics per employee
- Eliminated manual label generation
Highlights
- Serverless backend with scan + unique device tracking
- Printer-native ZPL generation for Zebra hardware
- Batch label generation grouped by store location
- QR routing with platform-aware redirects
