* Project Description: I’m looking for a skilled Python or Node.js developer to build a script that automates uploading 20,000+ email contacts and registering them as attendees for an Eventbrite event. The script should connect to the Eventbrite API, read contacts from a file, and automatically add each contact as a registered attendee. Proxy support is required to handle large uploads and avoid rate limits. - Key Features: Connect securely to the Eventbrite API (OAuth2 or API token) Read contact emails from a .txt or .csv file (20K+ entries) Automatically register each contact to a specific event (by link or event ID) Proxy rotation support to prevent IP blocking or API limits Progress logging (success/failure counts, errors, skipped contacts) Batch upload handling (multi-threaded or async requests) for performance Configurable settings (API key, event link, proxy list, file path) -Deliverables: 1 Fully working Python or Node.js script 2 Config file (API key, event link, proxy list, etc.) 3 Example input file (emails.txt) 4 Clear README / setup guide - Technical Requirements: Strong knowledge of Python (requests, aiohttp) or Node.js (axios, fetch) Experience working with Eventbrite API or other event/ticket APIs Handling of large datasets (20K+ records) efficiently Proxy rotation, asynchronous programming, and rate-limit control Clean, maintainable, and documented code
