Overview

An Express.js proxy service that receives IoT water-quality query parameters, formats them, and forwards them to an external Waterfit API.

Key features

• Device parameter ingestion for pH, TDS, temperature, voltages, turbidity, and flow rate
• External API forwarding with transformed response payloads
• Health-check endpoint for uptime monitoring
• Query parsing, error handling, and response formatting

What I owned

• Built Express routes for device parameter forwarding
• Integrated axios-based communication with external IoT services
• Added environment-driven configuration and health checks
• Documented sensor payload flow for production use
