Looking for an experienced JavaScript developer to build a custom script that can be run directly in the browser console on DealMachine's Leads page. The goal is to extract property records and mobile phone numbers from memory without scraping HTML or automating clicks, then export them as JSON or CSV.

Strong JavaScript experience, knowledge of inspecting window object or global application state for accessing data, familiarity with JSON processing and filtering logic (especially distinguishing mobile vs landline numbers), relevant project examples showing efficient in-memory extraction capabilities at scale.
