Project Overview:
AetherNest Spaces requires an expert Node.js developer to design and implement a robust API for integrating property listings from various external sources into our core real estate platform.

Requirements:
AetherNest Spaces is expanding, and we need an expert Node.js developer to build a new, robust RESTful API. This API will primarily handle the ingestion, processing, and serving of property listing data from various external sources into our core platform. We require someone highly skilled in scalable backend architecture, secure API design, and efficient data handling. Please connect with us to discuss our existing system architecture, specific data sources, and performance expectations.

Deliverables:
The key deliverable will be a production-ready, well-documented Node.js API complete with clear, tested endpoints for property data operations. We also expect comprehensive unit and integration tests. Let's chat to align on specific documentation standards and deployment procedures.

Please feel free to ask any clarifying questions in chat before submitting your proposal.
