Proxy Rotation Engine** * Support for ISP and Residential proxies * Sticky sessions + timed rotation + per-request rotation * Intelligent retry logic on bans/timeouts * Proxy pool management (health checks, scoring, auto-replacement) * Format support: host:port:user:pass **2. Multi-Session Browser Automation** * Use Playwright / Puppeteer (Playwright preferred) * Ability to run 20–100 concurrent sessions * Assign 1 proxy per session * Efficient resource usage (low CPU/RAM overhead) **3. Session Isolation** * Separate cookies, localStorage, indexedDB per session * Unique browser profiles per instance * Consistent fingerprint per session **4. Fingerprint & Anti-Detection** * Canvas, WebGL, Audio fingerprint spoofing * User-Agent, timezone, locale, viewport alignment * WebRTC leak prevention * Navigator/window object patching * Human-like interaction patterns (delays, randomness) **5. Network Layer Control** * Intercept and modify requests (headers, cookies, payloads) * Optimize request flow (remove unnecessary calls) * Ability to analyze XHR/fetch traffic **6. Anti-Bot Handling** * Experience handling Cloudflare/Akamai-style protections * Detect soft vs hard blocks * Smart retry/backoff strategies **7. Optional (Preferred)** * CAPTCHA solving integration (manual or assisted) * Basic dashboard/UI for monitoring sessions and proxies --- **Deliverables:** * Fully working system (not just scripts) * Clean, modular, maintainable code * Configurable proxy/session settings * Documentation for setup and usage --- **Requirements:** * Proven experience with similar systems * Strong knowledge of browser internals, networking, and automation * Ability to write efficient, scalable code --- **To Apply, Include:** * Your tech stack * Relevant past work (GitHub, demos, case studies) * Brief explanation of how you would approach this project --- ** Only serious developers with real-world experience should apply.

Hi. I can build this high-performance proxy rotator and anti-detection automation system for you. My experience with browser internals, fingerprint spoofing, and scalable web automation makes me a strong fit for this project. I am available to start immediately and can deliver a robust, isolated session management architecture. My approach involves using Playwright with a custom stealth plugin to patch navigator properties and prevent leaks. I will build a central proxy manager in Node.js to handle health checks and sticky session logic, ensuring each browser context maintains a consistent fingerprint and dedicated residential IP. I will implement request interception to strip tracking headers and optimise resource usage, while using a jitter-based human interaction layer to bypass behavioural analysis and Cloudflare protections. Tech Stack: TypeScript, Node.js, Playwright, Stealth-forks, Redis for session state, and Python for advanced data processing if needed. Relevant Past Work: I have built custom Chrome extensions and automation engines that successfully manage hundreds of concurrent sessions with unique hardware fingerprints and rotated residential proxies for high-frequency data extraction. cheers Nehal

I’ve worked on browser automation and proxy-based systems using Playwright and Node.js, focusing on session isolation, proxy rotation, and handling anti-detection mechanisms. I understand the challenges around fingerprinting, WebRTC leaks, and managing multiple concurrent sessions efficiently. For this project, I’d structure the system modularly—separating proxy management, session handling, and network interception—so it remains scalable and maintainable. I’ve also handled request interception and built systems that mimic human-like interaction patterns to reduce detection. I’m confident I can deliver a stable, efficient solution that meets your requirements without overengineering it.
