Backend Developer

Job Overview

We hate apps. We hate downloading shi*. And we hate making busy professionals learn another bloated interface. So do real estate agents.

• Agentic Workflows: Implement unified data syncs and multi-app automation pipelines using tools like Nango to abstract away APl maintenance.
• Web Automation & Scrutiny: Build and optimize headless browsing infrastructure (via Browserbase) to automate complex data retrieval and data-entry logistics on behalf of...
