We are seeking an experienced developer to build an automation system for creating accounts on IG and TT in batches (sizes of 10, 20, 50, or 100) as part of a marketing research initiative. The project involves setting up an end-to-end solution on a Hostinger VPS (Ubuntu) with a user-facing web dashboard for external users to request and track batch processing. The system will utilize Playwright with Node.js for browser automation, n8n for workflow orchestration, and integrate APIs for temporary data (emails, SMS verification) and proxy rotation to ensure scalability and avoid detection. Key Responsibilities: Set up a Hostinger VPS 4 (Ubuntu) environment with Node.js, Playwright, n8n, Nginx, and necessary dependencies. Design a lightweight database (SQLite or MySQL) or CSV-based storage for user data, batch requests, and account details (email, phone, username, password, status). Develop a user dashboard using React.js or Vue.js with an Express.js backend, featuring user authentication, batch size selection, status tracking, and CSV download of results; host on VPS with HTTPS via Let’s Encrypt. Build n8n workflows to handle batch requests via webhook, manage temporary data APIs, trigger Playwright scripts sequentially, and update users on completion with delays (5-10 minutes per account) to manage load. Integrate disposable email APIs (e.g., Temp-Mail.org) and SMS verification services (e.g., SMS-Activate.org, Twilio) with fallback logic for reliability. Write Playwright scripts in Node.js to automate sign-up processes on IG and TT platforms, incorporating random proxies, user agent spoofing, delayed actions, and error retries (up to 3 attempts). Implement proxy rotation using services like Smartproxy or Bright Data, with random selection per session and health checks for failed IPs. Ensure batch processing scales safely on VPS resources (4 cores, 8 GB RAM) by limiting concurrent tasks (1-3) and spacing larger batches over hours. Deploy all components (n8n, dashboard API, scripts) with PM2 or systemd for background operation and auto-restart on failure. Test with small batches (10 accounts) to optimize success rates, log actions for debugging, and monitor VPS resources (e.g., via htop). Provide documentation for users, admins, and developers, plus 1-2 weeks of post-launch support for adjustments or issue resolution. Skills Required: Strong experience with Node.js, Playwright, and browser automation for social media platforms. Proficiency in n8n for workflow automation or similar no-code tools. Expertise in frontend (React.js/Vue.js) and backend (Express.js) development for dashboard creation. Familiarity with proxy rotation, API integrations (email/SMS), and VPS setup (Ubuntu, Nginx, PM2). Understanding of anti-detection techniques (randomization, delays, IP management) for automation tasks. Prior work on social media automation or marketing tools is a plus.
