The System of Textnow Multi-Account Registration

I’m looking for an engineer who already knows the ins-and-outs of the Textnow protocol, understands how PerimeterX detects automated traffic, and has a proven track record building multi-account registration pipelines.

Project objective
I need a production-ready module that can create, verify, and manage large numbers of Textnow accounts while consistently evading PerimeterX anti-scraping barriers. The same core logic must plug into:
• our web dashboard,
• native iOS/Android apps, and
• a lightweight desktop (Electron) client.

Key focus areas
1. Textnow protocol integration – handle session initiation, SMS/voice verification, and any rotating tokens.
2. PerimeterX avoidance – craft request signatures, fingerprints, and cookie flows that remain valid under high concurrency.
3. Multi-account engine – queue management, retry logic, proxy rotation, and configurable rate limits.

Required deliverables
• Clean, well-documented source code (preferably Node.js or Python, but I’m open to other stacks if you can justify them).
• Automated tests that spin up multiple accounts in parallel and confirm success.
• A short technical read-me explaining setup, environment variables, and deployment for web, mobile, and desktop targets.
• Demo video or live session showing at least ten accounts created without triggering PerimeterX.

To help me choose quickly, please share:
• A brief note on previous Textnow or comparable VoIP/SMS integrations.
• Specific techniques you’ve used to bypass PerimeterX (feel free to redact sensitive details).
• Estimated delivery timeline and any third-party services you’ll need access to.

I’m ready to move fast and will provide prompt feedback on milestones and test runs.
Requirement: This project must be tested for 7 working days after delivery with no issues, and the payment will be settled in full at once.
