Rotating US Residential Proxy System

I need a production-ready distributed platform that delivers genuine US residential IPs which rotate automatically in the background. End-users will access the service by entering a simple username and password in their proxy settings; no extra API or desktop client is required right now. Core requirements • Pool and manage a large set of clean residential IPs located across the United States. • Issue a fresh IP on each request or at a configurable interval so customers always appear from a new address. • Authenticate every connection with traditional proxy credentials (user:pass) and reject anything else. • Track data transfer for each account in real time and log usage by the exact number of gigabytes consumed. • Expose accurate usage statistics to my billing module so customers can top up or be cut off when their data quota is reached. • Build the service to scale horizontally (micro-services or containerised nodes are fine) and fail over smoothly if one node drops. • Provide a lightweight admin dashboard where I can add or suspend accounts, view live traffic, and swap out IP sources. Acceptance criteria 1. A working proxy endpoint (HTTP and SOCKS5 preferred) that delivers rotating US residential IPs. 2. Successful authentication with username/password and proper data metering per user. 3. Dashboard shows connected sessions and cumulative GB usage with <1 % variance from actual traffic. 4. Clear deployment instructions and codebase that can be re-deployed to additional servers without manual tweaks. 5. Load test with at least 1 000 concurrent threads proves rotation and stability. Technologies are open, but I expect choices like Go, Node.js, or Rust for high-throughput proxy logic, Redis for session storage, and a CDN or container orchestration (Docker, Kubernetes) for easy scaling. If you have a better stack in mind, outline why it meets the same performance, security, and maintainability goals. Deliver the source code, Dockerfiles (if used), schema, and a short README so I can spin up the entire system on my own infrastructure.
