$70–$110/hr · Backend Development · posted by Helio Health

We receive readings from 12,000 connected devices through three vendor clouds, each with its own webhook format and quirks. We want a single, reliable ingestion service in front of our clinical database.

You will:

• Build a Node.js/TypeScript service that normalises vendor payloads

• Handle retries, duplicates and out-of-order readings

• Store raw and normalised data with an audit trail

• Add monitoring and alerts for silent devices

You need:

• Production Node.js and PostgreSQL experience

• Experience with webhook-heavy integrations

• Comfort working under HIPAA constraints (BAA required)

## Skills

Node.js, TypeScript, PostgreSQL, AWS, REST APIs
